This is the base class for service objects. Service objects are used to do
all requests to Storage. This class cannot be instantiated directly.

The storage account name. This is used to authenticate requests
signed with an account key and to construct the storage endpoint. It
is required unless a connection string is given, or if a custom
domain is used with anonymous authentication.
:ivar str account_key:
The storage account key. This is used for shared key authentication.
If neither account key or sas token is specified, anonymous access
will be used.

A shared access signature token to use to authenticate requests
instead of the account key. If account key and sas token are both
specified, account key will be used to sign. If neither are
specified, anonymous access will be used.
:ivar str primary_endpoint:
The endpoint to send storage requests to.
:ivar str secondary_endpoint:
The secondary endpoint to read storage data from. This will only be a
valid endpoint if the storage account used is RA-GRS and thus allows
reading from secondary.
:ivar function(context) retry:
A function which determines whether to retry. Takes as a parameter a
:class:`~azure.storage.common.models.RetryContext` object. Returns the number
of seconds to wait before retrying the request, or None to indicate not
to retry.
:ivar ~azure.storage.common.models.LocationMode location_mode:
The host location to use to make requests. Defaults to LocationMode.PRIMARY.
Note that this setting only applies to RA-GRS accounts as other account
types do not allow reading from secondary. If the location_mode is set to
LocationMode.SECONDARY, read requests will be sent to the secondary endpoint.
Write requests will continue to be sent to primary.
:ivar str protocol:
The protocol to use for requests. Defaults to https.
:ivar requests.Session request_session:
The session object to use for http requests.
:ivar function(request) request_callback:
A function called immediately before each request is sent. This function
takes as a parameter the request object and returns nothing. It may be
used to added custom headers or log request data.
:ivar function() response_callback:
A function called immediately after each response is received. This
function takes as a parameter the response object and returns nothing.
It may be used to log response data.
:ivar function() retry_callback:
A function called immediately after retry evaluation is performed. This
function takes as a parameter the retry context object and returns nothing.
It may be used to detect retries and log context information.

This is the main class managing Azure Table resources.
The Azure Table service offers structured storage in the form of tables. Tables
store data as collections of entities. Entities are similar to rows. An entity
has a primary key and a set of properties. A property is a name, typed-value pair,
similar to a column. The Table service does not enforce any schema for tables,
so two entities in the same table may have different sets of properties. Developers
may choose to enforce a schema on the client side. A table may contain any number
of entities.
:ivar object key_encryption_key:
The key-encryption-key optionally provided by the user. If provided, will be used to
encrypt/decrypt in supported methods.
For methods requiring decryption, either the key_encryption_key OR the resolver must be provided.
If both are provided, the resolver will take precedence.
Must implement the following methods for APIs requiring encryption:
wrap_key(key)--wraps the specified key (bytes) using an algorithm of the user's choice. Returns the encrypted key as bytes.
get_key_wrap_algorithm()--returns the algorithm used to wrap the specified symmetric key.
get_kid()--returns a string key id for this key-encryption-key.
Must implement the following methods for APIs requiring decryption:
unwrap_key(key, algorithm)--returns the unwrapped form of the specified symmetric key using the string-specified algorithm.
get_kid()--returns a string key id for this key-encryption-key.
:ivar function key_resolver_function(kid):
A function to resolve keys optionally provided by the user. If provided, will be used to decrypt in supported methods.
For methods requiring decryption, either the key_encryption_key OR
the resolver must be provided. If both are provided, the resolver will take precedence.
It uses the kid string to return a key-encryption-key implementing the interface defined above.
:ivar function(partition_key, row_key, property_name) encryption_resolver_functions:
A function that takes in an entity's partition key, row key, and property name and returns
a boolean that indicates whether that property should be encrypted.
:ivar bool require_encryption:
A flag that may be set to ensure that all messages successfully uploaded to the queue and all those downloaded and
successfully read from the queue are/were encrypted while on the server. If this flag is set, all required
parameters for encryption/decryption must be provided. See the above comments on the key_encryption_key and resolver.

An append blob is comprised of blocks and is optimized for append operations.
When you modify an append blob, blocks are added to the end of the blob only,
via the append_block operation. Updating or deleting of existing blocks is not
supported. Unlike a block blob, an append blob does not expose its block IDs.
Each block in an append blob can be a different size, up to a maximum of 4 MB,
and an append blob can include up to 50,000 blocks. The maximum size of an
append blob is therefore slightly more than 195 GB (4 MB X 50,000 blocks).

Block blobs let you upload large blobs efficiently. Block blobs are comprised
of blocks, each of which is identified by a block ID. You create or modify a
block blob by writing a set of blocks and committing them by their block IDs.
Each block can be a different size, up to a maximum of 4 MB, and a block blob
can include up to 50,000 blocks. The maximum size of a block blob is therefore
slightly more than 195 GB (4 MB X 50,000 blocks). If you are writing a block
blob that is no more than 64 MB in size, you can upload it in its entirety with
a single write operation; see create_blob_from_bytes.

Page blobs are a collection of 512-byte pages optimized for random read and
write operations. To create a page blob, you initialize the page blob and
specify the maximum size the page blob will grow. To add or update the
contents of a page blob, you write a page or pages by specifying an offset
and a range that align to 512-byte page boundaries. A write to a page blob
can overwrite just one page, some pages, or up to 4 MB of the page blob.
Writes to page blobs happen in-place and are immediately committed to the
blob. The maximum size for a page blob is 1 TB.

'''
Generates a shared access signature for the file.
Use the returned signature with the sas_token parameter of FileService.
:param str share_name:
Name of share.
:param str directory_name:
Name of directory. SAS tokens cannot be created for directories, so
this parameter should only be present if file_name is provided.
:param str file_name:
Name of file.
:param FilePermissions permission:
The permissions associated with the shared access signature. The
user is restricted to operations allowed by the permissions.
Permissions must be ordered read, create, write, delete, list.
Required unless an id is given referencing a stored access policy
which contains this field. This field must be omitted if it has been
specified in an associated stored access policy.
:param expiry:
The time at which the shared access signature becomes invalid.
Required unless an id is given referencing a stored access policy
which contains this field. This field must be omitted if it has
been specified in an associated stored access policy. Azure will always
convert values to UTC. If a date is passed in without timezone info, it
is assumed to be UTC.
:type expiry: date or str
:param start:
The time at which the shared access signature becomes valid. If
omitted, start time for this call is assumed to be the time when the
storage service receives the request. Azure will always convert values
to UTC. If a date is passed in without timezone info, it is assumed to
be UTC.
:type start: date or str
:param str id:
A unique value up to 64 characters in length that correlates to a
stored access policy. To create a stored access policy, use
set_file_service_properties.
:param str ip:
Specifies an IP address or a range of IP addresses from which to accept requests.
If the IP address from which the request originates does not match the IP address
or address range specified on the SAS token, the request is not authenticated.
For example, specifying sip=168.1.5.65 or sip=168.1.5.60-168.1.5.70 on the SAS
restricts the request to those IP addresses.
:param str protocol:
Specifies the protocol permitted for a request made. Possible values are
both HTTPS and HTTP (https,http) or HTTPS only (https). The default value
is https,http. Note that HTTP only is not a permitted value.
:param str cache_control:
Response header value for Cache-Control when resource is accessed
using this shared access signature.
:param str content_disposition:
Response header value for Content-Disposition when resource is accessed
using this shared access signature.
:param str content_encoding:
Response header value for Content-Encoding when resource is accessed
using this shared access signature.
:param str content_language:
Response header value for Content-Language when resource is accessed
using this shared access signature.
:param str content_type:
Response header value for Content-Type when resource is accessed
using this shared access signature.
:return: A Shared Access Signature (sas) token.

Azure Storage Analytics performs logging and provides metrics data for a storage

diagnose issues with your storage account. To use Storage Analytics, you must
enable it individually for each service you want to monitor.
The aggregated data is stored in a well-known blob (for logging) and in well-known
tables (for metrics), which may be accessed using the Blob service and Table
service APIs.
For an in-depth guide on using Storage Analytics and other tools to identify,
diagnose, and troubleshoot Azure Storage-related issues, see

A stored access policy can specify the start time, expiry time, and

specify all of these parameters within the stored access policy, and omit
them from the URL for the Shared Access Signature. Doing so permits you to
modify the associated signature's behavior at any time, as well as to revoke
it. Or you can specify one or more of the access policy parameters within
the stored access policy, and the others on the URL. Finally, you can
specify all of the parameters on the URL. In this case, you can use the
stored access policy to revoke the signature, but not to modify its behavior.
Together the Shared Access Signature and the stored access policy must
include all fields required to authenticate the signature. If any required
fields are missing, the request will fail. Likewise, if a field is specified
both in the Shared Access Signature URL and in the stored access policy, the
request will fail with status code 400 (Bad Request).

This is the main class managing queue resources.
The Queue service stores messages. A queue can contain an unlimited number of
messages, each of which can be up to 64KB in size. Messages are generally added
to the end of the queue and retrieved from the front of the queue, although
first in, first out (FIFO) behavior is not guaranteed.
:ivar function(data) encode_function:
A function used to encode queue messages. Takes as
a parameter the data passed to the put_message API and returns the encoded
message. Defaults to take text and xml encode, but bytes and other
encodings can be used. For example, base64 may be preferable for developing
across multiple Azure Storage libraries in different languages. See the
:class:`~azure.storage.queue.models.QueueMessageFormat` for xml, base64 and
no encoding methods as well as binary equivalents.
:ivar function(data) decode_function:
A function used to encode decode messages. Takes as
a parameter the data returned by the get_messages and peek_messages APIs and
returns the decoded message. Defaults to return text and xml decode, but
bytes and other decodings can be used. For example, base64 may be preferable
for developing across multiple Azure Storage libraries in different languages.

Generates a shared access signature for the account.
Use the returned signature with the sas_token parameter of the service

:param Services services:
Specifies the services accessible with the account SAS. You can
combine values to provide access to more than one service.
:param ResourceTypes resource_types:
Specifies the resource types that are accessible with the account
SAS. You can combine values to provide access to more than one
resource type.
:param AccountPermissions permission:
The permissions associated with the shared access signature. The
user is restricted to operations allowed by the permissions.
Required unless an id is given referencing a stored access policy
which contains this field. This field must be omitted if it has been
specified in an associated stored access policy. You can combine
values to provide more than one permission.
:param expiry:
The time at which the shared access signature becomes invalid.
Required unless an id is given referencing a stored access policy
which contains this field. This field must be omitted if it has
been specified in an associated stored access policy. Azure will always
convert values to UTC. If a date is passed in without timezone info, it
is assumed to be UTC.

:param start:
The time at which the shared access signature becomes valid. If
omitted, start time for this call is assumed to be the time when the
storage service receives the request. Azure will always convert values
to UTC. If a date is passed in without timezone info, it is assumed to
be UTC.
:type start: date or str
:param str ip:
Specifies an IP address or a range of IP addresses from which to accept requests.
If the IP address from which the request originates does not match the IP address
or address range specified on the SAS token, the request is not authenticated.
For example, specifying sip=168.1.5.65 or sip=168.1.5.60-168.1.5.70 on the SAS
restricts the request to those IP addresses.
:param str protocol:
Specifies the protocol permitted for a request made. The default value
is https,http. See :class:`~azure.storage.models.Protocol` for possible values.

This is the main class managing Azure Table resources.
The Azure Table service offers structured storage in the form of tables. Tables
store data as collections of entities. Entities are similar to rows. An entity
has a primary key and a set of properties. A property is a name, typed-value pair,
similar to a column. The Table service does not enforce any schema for tables,
so two entities in the same table may have different sets of properties. Developers
may choose to enforce a schema on the client side. A table may contain any number
of entities.

An append blob is comprised of blocks and is optimized for append operations.
When you modify an append blob, blocks are added to the end of the blob only,
via the append_block operation. Updating or deleting of existing blocks is not
supported. Unlike a block blob, an append blob does not expose its block IDs.
Each block in an append blob can be a different size, up to a maximum of 4 MB,
and an append blob can include up to 50,000 blocks. The maximum size of an
append blob is therefore slightly more than 195 GB (4 MB X 50,000 blocks).
:ivar int MAX_BLOCK_SIZE:
The size of the blocks put by append_blob_from_* methods. Smaller blocks
may be put if there is less data provided. The maximum block size the service
supports is 4MB.

This is the main class managing Blob resources.
The Blob service stores text and binary data as blobs in the cloud.
The Blob service offers the following three resources: the storage account,
containers, and blobs. Within your storage account, containers provide a
way to organize sets of blobs. For more information please see:
https://msdn.microsoft.com/en-us/library/azure/ee691964.aspx
:ivar int MAX_SINGLE_GET_SIZE:
The size of the first range get performed by get_blob_to_* methods if
max_connections is greater than 1. Less data will be returned if the
blob is smaller than this.
:ivar int MAX_CHUNK_GET_SIZE:
The size of subsequent range gets performed by get_blob_to_* methods if
max_connections is greater than 1 and the blob is larger than MAX_SINGLE_GET_SIZE.
Less data will be returned if the remainder of the blob is smaller than
this. If this is set to larger than 4MB, content_validation will throw an
error if enabled. However, if content_validation is not desired a size
greater than 4MB may be optimal. Setting this below 4MB is not recommended.
:ivar object key_encryption_key:
The key-encryption-key optionally provided by the user. If provided, will be used to
encrypt/decrypt in supported methods.
For methods requiring decryption, either the key_encryption_key OR the resolver must be provided.
If both are provided, the resolver will take precedence.
Must implement the following methods for APIs requiring encryption:
wrap_key(key)--wraps the specified key (bytes) using an algorithm of the user's choice. Returns the encrypted key as bytes.
get_key_wrap_algorithm()--returns the algorithm used to wrap the specified symmetric key.
get_kid()--returns a string key id for this key-encryption-key.
Must implement the following methods for APIs requiring decryption:
unwrap_key(key, algorithm)--returns the unwrapped form of the specified symmetric key using the string-specified algorithm.
get_kid()--returns a string key id for this key-encryption-key.
:ivar function key_resolver_function(kid):
A function to resolve keys optionally provided by the user. If provided, will be used to decrypt in supported methods.
For methods requiring decryption, either the key_encryption_key OR
the resolver must be provided. If both are provided, the resolver will take precedence.
It uses the kid string to return a key-encryption-key implementing the interface defined above.
:ivar bool require_encryption:
A flag that may be set to ensure that all messages successfully uploaded to the queue and all those downloaded and
successfully read from the queue are/were encrypted while on the server. If this flag is set, all required
parameters for encryption/decryption must be provided. See the above comments on the key_encryption_key and resolver.

If set to true, validates an MD5 hash for each retrieved portion of
the blob. This is primarily valuable for detecting bitflips on the wire
if using http instead of https as https (the default) will already

self.MAX_CHUNK_GET_SIZE instead of self.MAX_SINGLE_GET_SIZE. If
self.MAX_CHUNK_GET_SIZE was set to greater than 4MB an error will be
thrown. As computing the MD5 takes processing time and more requests
will need to be done due to the reduced chunk size there may be some
increase in latency.

the method returns at this point. If it is not, it will download the
remaining data parallel using the number of threads equal to
max_connections. Each chunk will be of size self.MAX_CHUNK_GET_SIZE.
If set to 1, a single large get request will be done. This is not
generally recommended but available if very few threads should be
used, network requests are very expensive, or a non-seekable stream
prevents parallel download. This may also be useful if many blobs are
expected to be empty as an extra request is required for empty blobs
if max_connections is greater than 1.

Required if the blob has an active lease.

Copies a blob asynchronously. This operation returns a copy operation
properties object, including a copy ID you can use to check or abort the
copy operation. The Blob service copies blobs on a best-effort basis.
The source blob for a copy operation may be a block blob, an append blob,
or a page blob. If the destination blob already exists, it must be of the
same blob type as the source blob. Any existing destination blob will be
overwritten. The destination blob cannot be modified while a copy operation
is in progress.
When copying from a page blob, the Blob service creates a destination page
blob of the source blob's length, initially containing all zeroes. Then
the source page ranges are enumerated, and non-empty ranges are copied.
For a block blob or an append blob, the Blob service creates a committed
blob of zero length before returning from this operation. When copying
from a block blob, all committed blocks and their block IDs are copied.
Uncommitted blocks are not copied. At the end of the copy operation, the
destination blob will have the same committed block count as the source.
When copying from an append blob, all committed blocks are copied. At the
end of the copy operation, the destination blob will have the same committed
block count as the source.
For all blob types, you can call get_blob_properties on the destination
blob to check the status of the copy operation. The final blob will be
committed when the copy completes.
:param str container_name:
Name of the destination container. The container must exist.
:param str blob_name:
Name of the destination blob. If the destination blob exists, it will
be overwritten. Otherwise, it will be created.
:param str copy_source:
A URL of up to 2 KB in length that specifies an Azure file or blob.
The value should be URL-encoded as it would appear in a request URI.
If the source is in another account, the source must either be public
or must be authenticated via a shared access signature. If the source
is public, no authentication is required.
Examples:
https://myaccount.blob.core.windows.net/mycontainer/myblob

https://otheraccount.blob.core.windows.net/mycontainer/myblob?sastoken

Block blobs let you upload large blobs efficiently. Block blobs are comprised
of blocks, each of which is identified by a block ID. You create or modify a
block blob by writing a set of blocks and committing them by their block IDs.
Each block can be a different size, up to a maximum of 4 MB, and a block blob
can include up to 50,000 blocks. The maximum size of a block blob is therefore
slightly more than 195 GB (4 MB X 50,000 blocks). If you are writing a block
blob that is no more than 64 MB in size, you can upload it in its entirety with
a single write operation; see create_blob_from_bytes.

The largest size upload supported in a single put call. This is used by
the create_blob_from_* methods if the content length is known and is less
than this value.
:ivar int MAX_BLOCK_SIZE:
The size of the blocks put by create_blob_from_* methods if the content
length is unknown or is larger than MAX_SINGLE_PUT_SIZE. Smaller blocks
may be put. The maximum block size the service supports is 100MB.
:ivar int MIN_LARGE_BLOCK_UPLOAD_THRESHOLD:
The minimum block size at which the the memory-optimized, block upload
algorithm is considered. This algorithm is only applicable to the create_blob_from_file and
create_blob_from_stream methods and will prevent the full buffering of blocks.
In addition to the block size, ContentMD5 validation and Encryption must be disabled as
these options require the blocks to be buffered.

The timeout parameter is expressed in seconds. This method may make

:param bool use_byte_buffer:
If True, this will force usage of the original full block buffering upload path.
By default, this value is False and will employ a memory-efficient,
streaming upload algorithm under the following conditions:
The provided stream is seekable, 'require_encryption' is False, and
MAX_BLOCK_SIZE >= MIN_LARGE_BLOCK_UPLOAD_THRESHOLD.
One should consider the drawbacks of using this approach. In order to achieve
memory-efficiency, a IOBase stream or file-like object is segmented into logical blocks
using a SubStream wrapper. In order to read the correct data, each SubStream must acquire
a lock so that it can safely seek to the right position on the shared, underlying stream.
If max_connections > 1, the concurrency will result in a considerable amount of seeking on
the underlying stream. For the most common inputs such as a file-like stream object, seeking
is an inexpensive operation and this is not much of a concern. However, for other variants of streams
this may not be the case. The trade-off for memory-efficiency must be weighed against the cost of seeking
with your input stream.
The SubStream class will attempt to buffer up to 4 MB internally to reduce the amount of
seek and read calls to the underlying stream. This is particularly beneficial when uploading larger blocks.

Page blobs are a collection of 512-byte pages optimized for random read and
write operations. To create a page blob, you initialize the page blob and
specify the maximum size the page blob will grow. To add or update the
contents of a page blob, you write a page or pages by specifying an offset
and a range that align to 512-byte page boundaries. A write to a page blob
can overwrite just one page, some pages, or up to 4 MB of the page blob.
Writes to page blobs happen in-place and are immediately committed to the
blob. The maximum size for a page blob is 1 TB.
:ivar int MAX_PAGE_SIZE:
The size of the pages put by create_blob_from_* methods. Smaller pages
may be put if there is less data provided. The maximum page size the service
supports is 4MB.

Copies a blob asynchronously. This operation returns a copy operation
properties object, including a copy ID you can use to check or abort the
copy operation. The Blob service copies blobs on a best-effort basis.
The source blob for a copy operation must be a page blob. If the destination
blob already exists, it must be of the same blob type as the source blob.
Any existing destination blob will be overwritten.
The destination blob cannot be modified while a copy operation is in progress.
When copying from a page blob, the Blob service creates a destination page
blob of the source blob's length, initially containing all zeroes. Then
the source page ranges are enumerated, and non-empty ranges are copied.
If the tier on the source blob is larger than the tier being passed to this
copy operation or if the size of the blob exceeds the tier being passed to
this copy operation then the operation will fail.
You can call get_blob_properties on the destination
blob to check the status of the copy operation. The final blob will be
committed when the copy completes.
:param str container_name:
Name of the destination container. The container must exist.
:param str blob_name:
Name of the destination blob. If the destination blob exists, it will

:param str copy_source:
A URL of up to 2 KB in length that specifies an Azure file or blob.
The value should be URL-encoded as it would appear in a request URI.
If the source is in another account, the source must either be public
or must be authenticated via a shared access signature. If the source
is public, no authentication is required.
Examples:
https://myaccount.blob.core.windows.net/mycontainer/myblob
https://myaccount.blob.core.windows.net/mycontainer/myblob?snapshot=
https://otheraccount.blob.core.windows.net/mycontainer/myblob?sastoken

Name-value pairs associated with the blob as metadata. If no name-value
pairs are specified, the operation will copy the metadata from the

If the destination blob has not been modified, the Blob service returns
status code 412 (Precondition Failed).
:param datetime destination_if_unmodified_since:
A DateTime value. Azure expects the date value passed in to be UTC.
If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.
Specify this conditional header to copy the blob only
if the destination blob has not been modified since the specified
date/time. If the destination blob has been modified, the Blob service
returns status code 412 (Precondition Failed).
:param ETag destination_if_match:
An ETag value, or the wildcard character (*). Specify an ETag value for
this conditional header to copy the blob only if the specified ETag value
matches the ETag value for an existing destination blob. If the ETag for
the destination blob does not match the ETag specified for If-Match, the
Blob service returns status code 412 (Precondition Failed).
:param ETag destination_if_none_match:
An ETag value, or the wildcard character (*). Specify an ETag value for

This is the base class for service objects. Service objects are used to do
all requests to Storage. This class cannot be instantiated directly.
:ivar str account_name:
The storage account name. This is used to authenticate requests
signed with an account key and to construct the storage endpoint. It
is required unless a connection string is given, or if a custom
domain is used with anonymous authentication.
:ivar str account_key:
The storage account key. This is used for shared key authentication.
If neither account key or sas token is specified, anonymous access
will be used.
:ivar str sas_token:
A shared access signature token to use to authenticate requests
instead of the account key. If account key and sas token are both
specified, account key will be used to sign. If neither are
specified, anonymous access will be used.
:ivar str primary_endpoint:
The endpoint to send storage requests to.
:ivar str secondary_endpoint:
The secondary endpoint to read storage data from. This will only be a
valid endpoint if the storage account used is RA-GRS and thus allows
reading from secondary.
:ivar function(context) retry:
A function which determines whether to retry. Takes as a parameter a
:class:`~azure.storage.common.models.RetryContext` object. Returns the number
of seconds to wait before retrying the request, or None to indicate not
to retry.
:ivar ~azure.storage.common.models.LocationMode location_mode:
The host location to use to make requests. Defaults to LocationMode.PRIMARY.
Note that this setting only applies to RA-GRS accounts as other account
types do not allow reading from secondary. If the location_mode is set to
LocationMode.SECONDARY, read requests will be sent to the secondary endpoint.
Write requests will continue to be sent to primary.
:ivar str protocol:
The protocol to use for requests. Defaults to https.
:ivar requests.Session request_session:
The session object to use for http requests.
:ivar function(request) request_callback:
A function called immediately before each request is sent. This function
takes as a parameter the request object and returns nothing. It may be
used to added custom headers or log request data.
:ivar function() response_callback:
A function called immediately after each response is received. This
function takes as a parameter the response object and returns nothing.
It may be used to log response data.
:ivar function() retry_callback:
A function called immediately after retry evaluation is performed. This
function takes as a parameter the retry context object and returns nothing.
It may be used to detect retries and log context information.

The Server Message Block (SMB) protocol is the preferred file share protocol
used on premise today. The Microsoft Azure File service enables customers to
leverage the availability and scalability of Azure's Cloud Infrastructure as
a Service (IaaS) SMB without having to rewrite SMB client applications.
The Azure File service also offers a compelling alternative to traditional
Direct Attached Storage (DAS) and Storage Area Network (SAN) solutions, which
are often complex and expensive to install, configure, and operate.

The size of subsequent range gets performed by get_file_to_* methods if
max_connections is greater than 1 and the file is larger than MAX_SINGLE_GET_SIZE.
Less data will be returned if the remainder of the file is smaller than
this. If this is set to larger than 4MB, content_validation will throw an

greater than 4MB may be optimal. Setting this below 4MB is not recommended.

Callback for progress with signature function(current, total) where
current is the number of bytes transfered so far and total is the
size of the file, or None if the total size is unknown.

:param int max_connections:
Maximum number of parallel connections to use. Note that parallel upload
requires the stream to be seekable.
:param int timeout:
The timeout parameter is expressed in seconds. This method may make
multiple calls to the Azure service and the timeout will apply to
each call individually.

This is the main class managing queue resources.
The Queue service stores messages. A queue can contain an unlimited number of
messages, each of which can be up to 64KB in size. Messages are generally added
to the end of the queue and retrieved from the front of the queue, although
first in, first out (FIFO) behavior is not guaranteed.
:ivar function(data) encode_function:
A function used to encode queue messages. Takes as
a parameter the data passed to the put_message API and returns the encoded
message. Defaults to take text and xml encode, but bytes and other
encodings can be used. For example, base64 may be preferable for developing
across multiple Azure Storage libraries in different languages. See the
:class:`~azure.storage.queue.models.QueueMessageFormat` for xml, base64 and
no encoding methods as well as binary equivalents.
:ivar function(data) decode_function:
A function used to encode decode messages. Takes as
a parameter the data returned by the get_messages and peek_messages APIs and
returns the decoded message. Defaults to return text and xml decode, but
bytes and other decodings can be used. For example, base64 may be preferable
for developing across multiple Azure Storage libraries in different languages.
See the :class:`~azure.storage.queue.models.QueueMessageFormat` for xml, base64
and no decoding methods as well as binary equivalents.
:ivar object key_encryption_key:
The key-encryption-key optionally provided by the user. If provided, will be used to
encrypt/decrypt in supported methods.
For methods requiring decryption, either the key_encryption_key OR the resolver must be provided.
If both are provided, the resolver will take precedence.
Must implement the following methods for APIs requiring encryption:
wrap_key(key)--wraps the specified key (bytes) using an algorithm of the user's choice. Returns the encrypted key as bytes.
get_key_wrap_algorithm()--returns the algorithm used to wrap the specified symmetric key.
get_kid()--returns a string key id for this key-encryption-key.
Must implement the following methods for APIs requiring decryption:
unwrap_key(key, algorithm)--returns the unwrapped form of the specified symmetric key using the string-specified algorithm.
get_kid()--returns a string key id for this key-encryption-key.
:ivar function key_resolver_function(kid):
A function to resolve keys optionally provided by the user. If provided, will be used to decrypt in supported methods.
For methods requiring decryption, either the key_encryption_key OR
the resolver must be provided. If both are provided, the resolver will take precedence.
It uses the kid string to return a key-encryption-key implementing the interface defined above.
:ivar bool require_encryption:
A flag that may be set to ensure that all messages successfully uploaded to the queue and all those downloaded and
successfully read from the queue are/were encrypted while on the server. If this flag is set, all required
parameters for encryption/decryption must be provided. See the above comments on the key_encryption_key and resolver.

Updates the visibility timeout of a message. You can also use this
operation to update the contents of a message.
This operation can be used to continually extend the invisibility of a
queue message. This functionality can be useful if you want a worker role
to "lease" a queue message. For example, if a worker role calls get_messages
and recognizes that it needs more time to process a message, it can
continually extend the message's invisibility until it is processed. If
the worker role were to fail during processing, eventually the message
would become visible again and another worker role could process it.
If the key-encryption-key field is set on the local service object, this method will
encrypt the content before uploading.
:param str queue_name:
The name of the queue containing the message to update.
:param str message_id:
The message id identifying the message to update.
:param str pop_receipt:
A valid pop receipt value returned from an earlier call
to the :func:`~get_messages` or :func:`~update_message` operation.
:param int visibility_timeout:
Specifies the new visibility timeout value, in seconds,
relative to server time. The new value must be larger than or equal
to 0, and cannot be larger than 7 days. The visibility timeout of a
message cannot be set to a value later than the expiry time. A
message can be updated until it has been deleted or has expired.
:param obj content:
Message content. Allowed type is determined by the encode_function
set on the service. Default is str.
:param int timeout:
The server timeout, expressed in seconds.
:return:
A list of :class:`~azure.storage.queue.models.QueueMessage` objects. For convenience,
this object is also populated with the content, although it is not returned by the service.

'''
An append blob is comprised of blocks and is optimized for append operations.
When you modify an append blob, blocks are added to the end of the blob only,
via the append_block operation. Updating or deleting of existing blocks is not
supported. Unlike a block blob, an append blob does not expose its block IDs.
Each block in an append blob can be a different size, up to a maximum of 4 MB,
and an append blob can include up to 50,000 blocks. The maximum size of an
append blob is therefore slightly more than 195 GB (4 MB X 50,000 blocks).
:ivar int MAX_BLOCK_SIZE:
The size of the blocks put by append_blob_from_* methods. Smaller blocks
may be put if there is less data provided. The maximum block size the service
supports is 4MB.

This is the main class managing Blob resources.
The Blob service stores text and binary data as blobs in the cloud.
The Blob service offers the following three resources: the storage account,
containers, and blobs. Within your storage account, containers provide a
way to organize sets of blobs. For more information please see:
https://msdn.microsoft.com/en-us/library/azure/ee691964.aspx
:ivar int MAX_SINGLE_GET_SIZE:
The size of the first range get performed by get_blob_to_* methods if
max_connections is greater than 1. Less data will be returned if the
blob is smaller than this.
:ivar int MAX_CHUNK_GET_SIZE:
The size of subsequent range gets performed by get_blob_to_* methods if
max_connections is greater than 1 and the blob is larger than MAX_SINGLE_GET_SIZE.
Less data will be returned if the remainder of the blob is smaller than
this. If this is set to larger than 4MB, content_validation will throw an
error if enabled. However, if content_validation is not desired a size

The key-encryption-key optionally provided by the user. If provided, will be used to
encrypt/decrypt in supported methods.
For methods requiring decryption, either the key_encryption_key OR the resolver must be provided.
If both are provided, the resolver will take precedence.
Must implement the following methods for APIs requiring encryption:
wrap_key(key)--wraps the specified key (bytes) using an algorithm of the user's choice. Returns the encrypted key as bytes.
get_key_wrap_algorithm()--returns the algorithm used to wrap the specified symmetric key.
get_kid()--returns a string key id for this key-encryption-key.
Must implement the following methods for APIs requiring decryption:
unwrap_key(key, algorithm)--returns the unwrapped form of the specified symmetric key using the string-specified algorithm.
get_kid()--returns a string key id for this key-encryption-key.
:ivar function key_resolver_function(kid):
A function to resolve keys optionally provided by the user. If provided, will be used to decrypt in supported methods.
For methods requiring decryption, either the key_encryption_key OR
the resolver must be provided. If both are provided, the resolver will take precedence.
It uses the kid string to return a key-encryption-key implementing the interface defined above.

Establishes and manages a lease on a container.
The Lease Container operation can be called in one of five modes
Acquire, to request a new lease
Renew, to renew an existing lease
Change, to change the ID of an existing lease
Release, to free the lease if it is no longer needed so that another
client may immediately acquire a lease against the container
Break, to end the lease but ensure that another client cannot acquire
a new lease until the current lease period has expired

Possible _LeaseActions values: acquire|renew|release|break|change
:param str lease_id:
Required if the container has an active lease.

Specifies the duration of the lease, in seconds, or negative one

between 15 and 60 seconds. A lease duration cannot be changed
using renew or change. For backwards compatibility, the default is
60, and the value is only used on an acquire operation.

For a break operation, this is the proposed duration of
seconds that the lease should continue before it is broken, between

on the lease is used. A new lease will not be available before the
break period has expired, but the lease may be held for longer than
the break period. If this header does not appear with a break
operation, a fixed-duration lease breaks after the remaining lease
period elapses, and an infinite lease breaks immediately.

The snapshot parameter is an opaque DateTime value that,
when present, specifies the blob snapshot to retrieve.
:param int start_range:
Start of byte range to use for downloading a section of the blob.
If no end_range is given, all bytes after the start_range will be downloaded.
The start_range and end_range params are inclusive.
Ex: start_range=0, end_range=511 will download first 512 bytes of blob.
:param int end_range:
End of byte range to use for downloading a section of the blob.
If end_range is given, start_range must be provided.
The start_range and end_range params are inclusive.
Ex: start_range=0, end_range=511 will download first 512 bytes of blob.
:param bool validate_content:
If set to true, validates an MD5 hash for each retrieved portion of
the blob. This is primarily valuable for detecting bitflips on the wire
if using http instead of https as https (the default) will already
validate. Note that the service will only return transactional MD5s
for chunks 4MB or less so the first get request will be of size
self.MAX_CHUNK_GET_SIZE instead of self.MAX_SINGLE_GET_SIZE. If
self.MAX_CHUNK_GET_SIZE was set to greater than 4MB an error will be
thrown. As computing the MD5 takes processing time and more requests
will need to be done due to the reduced chunk size there may be some
increase in latency.
:param progress_callback:
Callback for progress with signature function(current, total)
where current is the number of bytes transfered so far, and total is
the size of the blob if known.
:type progress_callback: func(current, total)
:param int max_connections:
If set to 2 or greater, an initial get will be done for the first
self.MAX_SINGLE_GET_SIZE bytes of the blob. If this is the entire blob,
the method returns at this point. If it is not, it will download the
remaining data parallel using the number of threads equal to
max_connections. Each chunk will be of size self.MAX_CHUNK_GET_SIZE.
If set to 1, a single large get request will be done. This is not
generally recommended but available if very few threads should be
used, network requests are very expensive, or a non-seekable stream
prevents parallel download. This may also be useful if many blobs are
expected to be empty as an extra request is required for empty blobs
if max_connections is greater than 1.
:param str lease_id:
Required if the blob has an active lease.
:param datetime if_modified_since:
A DateTime value. Azure expects the date value passed in to be UTC.
If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.
Specify this header to perform the operation only
if the resource has been modified since the specified time.
:param datetime if_unmodified_since:
A DateTime value. Azure expects the date value passed in to be UTC.
If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.
Specify this header to perform the operation only if
the resource has not been modified since the specified date/time.
:param str if_match:
An ETag value, or the wildcard character (*). Specify this header to perform
the operation only if the resource's ETag matches the value specified.
:param str if_none_match:
An ETag value, or the wildcard character (*). Specify this header
to perform the operation only if the resource's ETag does not match
the value specified. Specify the wildcard character (*) to perform
the operation only if the resource does not exist, and fail the
operation if it does exist.
:param int timeout:
The timeout parameter is expressed in seconds. This method may make
multiple calls to the Azure service and the timeout will apply to
each call individually.
:return: A Blob with properties and metadata. If max_connections is greater
than 1, the content_md5 (if set on the blob) will not be returned. If you
require this value, either use get_blob_properties or set max_connections
to 1.

Establishes and manages a lease on a blob for write and delete operations.
The Lease Blob operation can be called in one of five modes:
Acquire, to request a new lease.
Renew, to renew an existing lease.
Change, to change the ID of an existing lease.
Release, to free the lease if it is no longer needed so that another
client may immediately acquire a lease against the blob.
Break, to end the lease but ensure that another client cannot acquire
a new lease until the current lease period has expired.

For a break operation, this is the proposed duration of
seconds that the lease should continue before it is broken, between

the break period. If this header does not appear with a break

Copies a blob asynchronously. This operation returns a copy operation
properties object, including a copy ID you can use to check or abort the
copy operation. The Blob service copies blobs on a best-effort basis.
The source blob for a copy operation may be a block blob, an append blob,
or a page blob. If the destination blob already exists, it must be of the
same blob type as the source blob. Any existing destination blob will be
overwritten. The destination blob cannot be modified while a copy operation
is in progress.
When copying from a page blob, the Blob service creates a destination page
blob of the source blob's length, initially containing all zeroes. Then
the source page ranges are enumerated, and non-empty ranges are copied.
For a block blob or an append blob, the Blob service creates a committed
blob of zero length before returning from this operation. When copying
from a block blob, all committed blocks and their block IDs are copied.
Uncommitted blocks are not copied. At the end of the copy operation, the
destination blob will have the same committed block count as the source.
When copying from an append blob, all committed blocks are copied. At the
end of the copy operation, the destination blob will have the same committed
block count as the source.
For all blob types, you can call get_blob_properties on the destination
blob to check the status of the copy operation. The final blob will be
committed when the copy completes.
:param str container_name:
Name of the destination container. The container must exist.
:param str blob_name:
Name of the destination blob. If the destination blob exists, it will
be overwritten. Otherwise, it will be created.
:param str copy_source:
A URL of up to 2 KB in length that specifies an Azure file or blob.
The value should be URL-encoded as it would appear in a request URI.
If the source is in another account, the source must either be public
or must be authenticated via a shared access signature. If the source
is public, no authentication is required.
Examples:
https://myaccount.blob.core.windows.net/mycontainer/myblob
https://myaccount.blob.core.windows.net/mycontainer/myblob?snapshot=
https://otheraccount.blob.core.windows.net/mycontainer/myblob?sastoken

metadata, and metadata is not copied from the source blob or file.

Block blobs let you upload large blobs efficiently. Block blobs are comprised
of blocks, each of which is identified by a block ID. You create or modify a
block blob by writing a set of blocks and committing them by their block IDs.
Each block can be a different size, up to a maximum of 100 MB, and a block blob
can include up to 50,000 blocks. The maximum size of a block blob is therefore
approximately 4.75 TB (100 MB X 50,000 blocks). If you are writing a block
blob that is no more than 64 MB in size, you can upload it in its entirety with
a single write operation; see create_blob_from_bytes.
:ivar int MAX_SINGLE_PUT_SIZE:
The largest size upload supported in a single put call. This is used by
the create_blob_from_* methods if the content length is known and is less
than this value.
:ivar int MAX_BLOCK_SIZE:
The size of the blocks put by create_blob_from_* methods if the content
length is unknown or is larger than MAX_SINGLE_PUT_SIZE. Smaller blocks
may be put. The maximum block size the service supports is 100MB.
:ivar int MIN_LARGE_BLOCK_UPLOAD_THRESHOLD:
The minimum block size at which the the memory-optimized, block upload
algorithm is considered. This algorithm is only applicable to the create_blob_from_file and
create_blob_from_stream methods and will prevent the full buffering of blocks.
In addition to the block size, ContentMD5 validation and Encryption must be disabled as
these options require the blocks to be buffered.

The timeout parameter is expressed in seconds. This method may make

:param bool use_byte_buffer:
If True, this will force usage of the original full block buffering upload path.
By default, this value is False and will employ a memory-efficient,
streaming upload algorithm under the following conditions:
The provided stream is seekable, 'require_encryption' is False, and
MAX_BLOCK_SIZE >= MIN_LARGE_BLOCK_UPLOAD_THRESHOLD.
One should consider the drawbacks of using this approach. In order to achieve
memory-efficiency, a IOBase stream or file-like object is segmented into logical blocks
using a SubStream wrapper. In order to read the correct data, each SubStream must acquire
a lock so that it can safely seek to the right position on the shared, underlying stream.
If max_connections > 1, the concurrency will result in a considerable amount of seeking on
the underlying stream. For the most common inputs such as a file-like stream object, seeking
is an inexpensive operation and this is not much of a concern. However, for other variants of streams
this may not be the case. The trade-off for memory-efficiency must be weighed against the cost of seeking
with your input stream.
The SubStream class will attempt to buffer up to 4 MB internally to reduce the amount of
seek and read calls to the underlying stream. This is particularly beneficial when uploading larger blocks.

Copies a blob asynchronously. This operation returns a copy operation
properties object, including a copy ID you can use to check or abort the
copy operation. The Blob service copies blobs on a best-effort basis.
The source blob for a copy operation must be a page blob. If the destination
blob already exists, it must be of the same blob type as the source blob.
Any existing destination blob will be overwritten.
The destination blob cannot be modified while a copy operation is in progress.
When copying from a page blob, the Blob service creates a destination page
blob of the source blob's length, initially containing all zeroes. Then
the source page ranges are enumerated, and non-empty ranges are copied.
If the tier on the source blob is larger than the tier being passed to this
copy operation or if the size of the blob exceeds the tier being passed to
this copy operation then the operation will fail.
You can call get_blob_properties on the destination
blob to check the status of the copy operation. The final blob will be
committed when the copy completes.
:param str container_name:
Name of the destination container. The container must exist.
:param str blob_name:
Name of the destination blob. If the destination blob exists, it will
be overwritten. Otherwise, it will be created.
:param str copy_source:
A URL of up to 2 KB in length that specifies an Azure file or blob.
The value should be URL-encoded as it would appear in a request URI.
If the source is in another account, the source must either be public
or must be authenticated via a shared access signature. If the source
is public, no authentication is required.
Examples:
https://myaccount.blob.core.windows.net/mycontainer/myblob
https://myaccount.blob.core.windows.net/mycontainer/myblob?snapshot=
https://otheraccount.blob.core.windows.net/mycontainer/myblob?sastoken
:param metadata:
Name-value pairs associated with the blob as metadata. If no name-value
pairs are specified, the operation will copy the metadata from the
source blob or file to the destination blob. If one or more name-value
pairs are specified, the destination blob is created with the specified
metadata, and metadata is not copied from the source blob or file.
:type metadata: dict(str, str).

Specify this conditional header to copy the blob only if the source blob
has not been modified since the specified date/time.
:param ETag source_if_match:
An ETag value, or the wildcard character (*). Specify this conditional
header to copy the source blob only if its ETag matches the value
specified. If the ETag values do not match, the Blob service returns
status code 412 (Precondition Failed). This header cannot be specified
if the source is an Azure File.
:param ETag source_if_none_match:
An ETag value, or the wildcard character (*). Specify this conditional

If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.
Specify this conditional header to copy the blob only
if the destination blob has been modified since the specified date/time.
If the destination blob has not been modified, the Blob service returns
status code 412 (Precondition Failed).
:param datetime destination_if_unmodified_since:
A DateTime value. Azure expects the date value passed in to be UTC.
If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.
Specify this conditional header to copy the blob only
if the destination blob has not been modified since the specified
date/time. If the destination blob has been modified, the Blob service
returns status code 412 (Precondition Failed).
:param ETag destination_if_match:
An ETag value, or the wildcard character (*). Specify an ETag value for
this conditional header to copy the blob only if the specified ETag value
matches the ETag value for an existing destination blob. If the ETag for
the destination blob does not match the ETag specified for If-Match, the
Blob service returns status code 412 (Precondition Failed).
:param ETag destination_if_none_match:
An ETag value, or the wildcard character (*). Specify an ETag value for
this conditional header to copy the blob only if the specified ETag value
does not match the ETag value for the destination blob. Specify the wildcard
character (*) to perform the operation only if the destination blob does not
exist. If the specified condition isn't met, the Blob service returns status
code 412 (Precondition Failed).
:param str destination_lease_id:
The lease ID specified for this header must match the lease ID of the
destination blob. If the request does not include the lease ID or it is not
valid, the operation fails with status code 412 (Precondition Failed).

This is the base class for service objects. Service objects are used to do
all requests to Storage. This class cannot be instantiated directly.
:ivar str account_name:
The storage account name. This is used to authenticate requests
signed with an account key and to construct the storage endpoint. It
is required unless a connection string is given, or if a custom
domain is used with anonymous authentication.
:ivar str account_key:
The storage account key. This is used for shared key authentication.
If neither account key or sas token is specified, anonymous access
will be used.
:ivar str sas_token:
A shared access signature token to use to authenticate requests
instead of the account key. If account key and sas token are both
specified, account key will be used to sign. If neither are
specified, anonymous access will be used.
:ivar str primary_endpoint:
The endpoint to send storage requests to.
:ivar str secondary_endpoint:
The secondary endpoint to read storage data from. This will only be a
valid endpoint if the storage account used is RA-GRS and thus allows
reading from secondary.
:ivar function(context) retry:
A function which determines whether to retry. Takes as a parameter a
:class:`~azure.storage.common.models.RetryContext` object. Returns the number
of seconds to wait before retrying the request, or None to indicate not
to retry.
:ivar ~azure.storage.common.models.LocationMode location_mode:
The host location to use to make requests. Defaults to LocationMode.PRIMARY.
Note that this setting only applies to RA-GRS accounts as other account
types do not allow reading from secondary. If the location_mode is set to
LocationMode.SECONDARY, read requests will be sent to the secondary endpoint.
Write requests will continue to be sent to primary.
:ivar str protocol:
The protocol to use for requests. Defaults to https.
:ivar requests.Session request_session:
The session object to use for http requests.
:ivar function(request) request_callback:
A function called immediately before each request is sent. This function
takes as a parameter the request object and returns nothing. It may be
used to added custom headers or log request data.
:ivar function() response_callback:
A function called immediately after each response is received. This
function takes as a parameter the response object and returns nothing.
It may be used to log response data.
:ivar function() retry_callback:
A function called immediately after retry evaluation is performed. This
function takes as a parameter the retry context object and returns nothing.
It may be used to detect retries and log context information.

The Server Message Block (SMB) protocol is the preferred file share protocol
used on premise today. The Microsoft Azure File service enables customers to
leverage the availability and scalability of Azure's Cloud Infrastructure as
a Service (IaaS) SMB without having to rewrite SMB client applications.
The Azure File service also offers a compelling alternative to traditional
Direct Attached Storage (DAS) and Storage Area Network (SAN) solutions, which
are often complex and expensive to install, configure, and operate.

:param str directory_name:
The path to the directory.
:param str file_name:
Name of existing file.
:param str file_path:
Path of file to write to.
:param str open_mode:
Mode to use when opening the file. Note that specifying append only
open_mode prevents parallel download. So, max_connections must be set
to 1 if this open_mode is used.
:param int start_range:
Start of byte range to use for downloading a section of the file.
If no end_range is given, all bytes after the start_range will be downloaded.
The start_range and end_range params are inclusive.
Ex: start_range=0, end_range=511 will download first 512 bytes of file.
:param int end_range:
End of byte range to use for downloading a section of the file.
If end_range is given, start_range must be provided.
The start_range and end_range params are inclusive.
Ex: start_range=0, end_range=511 will download first 512 bytes of file.
:param bool validate_content:
If set to true, validates an MD5 hash for each retrieved portion of
the file. This is primarily valuable for detecting bitflips on the wire
if using http instead of https as https (the default) will already
validate. Note that the service will only return transactional MD5s
for chunks 4MB or less so the first get request will be of size
self.MAX_CHUNK_GET_SIZE instead of self.MAX_SINGLE_GET_SIZE. If
self.MAX_CHUNK_GET_SIZE was set to greater than 4MB an error will be
thrown. As computing the MD5 takes processing time and more requests
will need to be done due to the reduced chunk size there may be some
increase in latency.

Callback for progress with signature function(current, total)
where current is the number of bytes transfered so far, and total is
the size of the file if known.

If set to 2 or greater, an initial get will be done for the first
self.MAX_SINGLE_GET_SIZE bytes of the file. If this is the entire file,
the method returns at this point. If it is not, it will download the
remaining data parallel using the number of threads equal to
max_connections. Each chunk will be of size self.MAX_CHUNK_GET_SIZE.
If set to 1, a single large get request will be done. This is not
generally recommended but available if very few threads should be
used, network requests are very expensive, or a non-seekable stream
prevents parallel download. This may also be valuable if the file is
being concurrently modified to enforce atomicity or if many files are
expected to be empty as an extra request is required for empty files
if max_connections is greater than 1.

This is the main class managing queue resources.
The Queue service stores messages. A queue can contain an unlimited number of
messages, each of which can be up to 64KB in size. Messages are generally added
to the end of the queue and retrieved from the front of the queue, although
first in, first out (FIFO) behavior is not guaranteed.
:ivar function(data) encode_function:
A function used to encode queue messages. Takes as
a parameter the data passed to the put_message API and returns the encoded
message. Defaults to take text and xml encode, but bytes and other
encodings can be used. For example, base64 may be preferable for developing
across multiple Azure Storage libraries in different languages. See the
:class:`~azure.storage.queue.models.QueueMessageFormat` for xml, base64 and
no encoding methods as well as binary equivalents.
:ivar function(data) decode_function:
A function used to encode decode messages. Takes as
a parameter the data returned by the get_messages and peek_messages APIs and
returns the decoded message. Defaults to return text and xml decode, but
bytes and other decodings can be used. For example, base64 may be preferable
for developing across multiple Azure Storage libraries in different languages.
See the :class:`~azure.storage.queue.models.QueueMessageFormat` for xml, base64
and no decoding methods as well as binary equivalents.
:ivar object key_encryption_key:
The key-encryption-key optionally provided by the user. If provided, will be used to
encrypt/decrypt in supported methods.
For methods requiring decryption, either the key_encryption_key OR the resolver must be provided.
If both are provided, the resolver will take precedence.
Must implement the following methods for APIs requiring encryption:
wrap_key(key)--wraps the specified key (bytes) using an algorithm of the user's choice. Returns the encrypted key as bytes.
get_key_wrap_algorithm()--returns the algorithm used to wrap the specified symmetric key.
get_kid()--returns a string key id for this key-encryption-key.
Must implement the following methods for APIs requiring decryption:
unwrap_key(key, algorithm)--returns the unwrapped form of the specified symmetric key using the string-specified algorithm.
get_kid()--returns a string key id for this key-encryption-key.
:ivar function key_resolver_function(kid):
A function to resolve keys optionally provided by the user. If provided, will be used to decrypt in supported methods.
For methods requiring decryption, either the key_encryption_key OR
the resolver must be provided. If both are provided, the resolver will take precedence.
It uses the kid string to return a key-encryption-key implementing the interface defined above.
:ivar bool require_encryption:
A flag that may be set to ensure that all messages successfully uploaded to the queue and all those downloaded and
successfully read from the queue are/were encrypted while on the server. If this flag is set, all required
parameters for encryption/decryption must be provided. See the above comments on the key_encryption_key and resolver.

'''
An append blob is comprised of blocks and is optimized for append operations.
When you modify an append blob, blocks are added to the end of the blob only,
via the append_block operation. Updating or deleting of existing blocks is not
supported. Unlike a block blob, an append blob does not expose its block IDs.
Each block in an append blob can be a different size, up to a maximum of 4 MB,
and an append blob can include up to 50,000 blocks. The maximum size of an
append blob is therefore slightly more than 195 GB (4 MB X 50,000 blocks).
:ivar int MAX_BLOCK_SIZE:
The size of the blocks put by append_blob_from_* methods. Smaller blocks
may be put if there is less data provided. The maximum block size the service
supports is 4MB.

The storage account key. This is used for shared key authentication.
If neither account key or sas token is specified, anonymous access
will be used.
:param str sas_token:
A shared access signature token to use to authenticate requests
instead of the account key. If account key and sas token are both
specified, account key will be used to sign. If neither are
specified, anonymous access will be used.

The custom domain to use. This can be set in the Azure Portal. For
example, 'www.mydomain.com'.

If specified, this will override all other parameters besides
request session. See
http://azure.microsoft.com/en-us/documentation/articles/storage-configure-connection-string/

If specified, this will override the default socket timeout. The timeout specified is in seconds.

the wire if using http instead of https as https (the default) will
already validate. Note that this MD5 hash is not stored with the
blob.

Conditional header. The max length in bytes permitted for
the append blob. If the Append Block operation would cause the blob
to exceed that limit or if the blob size is already greater than the
value specified in this header, the request will fail with
MaxBlobSizeConditionNotMet error (HTTP status code 412 - Precondition Failed).

This is the main class managing Blob resources.
The Blob service stores text and binary data as blobs in the cloud.
The Blob service offers the following three resources: the storage account,
containers, and blobs. Within your storage account, containers provide a
way to organize sets of blobs. For more information please see:
https://msdn.microsoft.com/en-us/library/azure/ee691964.aspx
:ivar int MAX_SINGLE_GET_SIZE:
The size of the first range get performed by get_blob_to_* methods if
max_connections is greater than 1. Less data will be returned if the
blob is smaller than this.
:ivar int MAX_CHUNK_GET_SIZE:
The size of subsequent range gets performed by get_blob_to_* methods if
max_connections is greater than 1 and the blob is larger than MAX_SINGLE_GET_SIZE.
Less data will be returned if the remainder of the blob is smaller than
this. If this is set to larger than 4MB, content_validation will throw an
error if enabled. However, if content_validation is not desired a size
greater than 4MB may be optimal. Setting this below 4MB is not recommended.
:ivar object key_encryption_key:
The key-encryption-key optionally provided by the user. If provided, will be used to
encrypt/decrypt in supported methods.
For methods requiring decryption, either the key_encryption_key OR the resolver must be provided.
If both are provided, the resolver will take precedence.
Must implement the following methods for APIs requiring encryption:
wrap_key(key)--wraps the specified key (bytes) using an algorithm of the user's choice. Returns the encrypted key as bytes.
get_key_wrap_algorithm()--returns the algorithm used to wrap the specified symmetric key.
get_kid()--returns a string key id for this key-encryption-key.
Must implement the following methods for APIs requiring decryption:
unwrap_key(key, algorithm)--returns the unwrapped form of the specified symmetric key using the string-specified algorithm.
get_kid()--returns a string key id for this key-encryption-key.
:ivar function key_resolver_function(kid):
A function to resolve keys optionally provided by the user. If provided, will be used to decrypt in supported methods.
For methods requiring decryption, either the key_encryption_key OR
the resolver must be provided. If both are provided, the resolver will take precedence.
It uses the kid string to return a key-encryption-key implementing the interface defined above.
:ivar bool require_encryption:
A flag that may be set to ensure that all messages successfully uploaded to the queue and all those downloaded and
successfully read from the queue are/were encrypted while on the server. If this flag is set, all required
parameters for encryption/decryption must be provided. See the above comments on the key_encryption_key and resolver.

If set to true, validates an MD5 hash for each retrieved portion of
the blob. This is primarily valuable for detecting bitflips on the wire
if using http instead of https as https (the default) will already
validate. Note that the service will only return transactional MD5s

self.MAX_CHUNK_GET_SIZE instead of self.MAX_SINGLE_GET_SIZE. If

thrown. As computing the MD5 takes processing time and more requests

increase in latency.

If set to 2 or greater, an initial get will be done for the first
self.MAX_SINGLE_GET_SIZE bytes of the blob. If this is the entire blob,
the method returns at this point. If it is not, it will download the
remaining data parallel using the number of threads equal to
max_connections. Each chunk will be of size self.MAX_CHUNK_GET_SIZE.
If set to 1, a single large get request will be done. This is not
generally recommended but available if very few threads should be
used, network requests are very expensive, or a non-seekable stream
prevents parallel download. This may also be useful if many blobs are
expected to be empty as an extra request is required for empty blobs
if max_connections is greater than 1.

Downloads a blob to a stream, with automatic chunking and progress
notifications. Returns an instance of :class:`~azure.storage.blob.models.Blob` with
properties and metadata.
:param str container_name:
Name of existing container.
:param str blob_name:
Name of existing blob.
:param io.IOBase stream:
Opened stream to write to.
:param str snapshot:
The snapshot parameter is an opaque DateTime value that,
when present, specifies the blob snapshot to retrieve.
:param int start_range:
Start of byte range to use for downloading a section of the blob.
If no end_range is given, all bytes after the start_range will be downloaded.
The start_range and end_range params are inclusive.
Ex: start_range=0, end_range=511 will download first 512 bytes of blob.
:param int end_range:
End of byte range to use for downloading a section of the blob.
If end_range is given, start_range must be provided.
The start_range and end_range params are inclusive.
Ex: start_range=0, end_range=511 will download first 512 bytes of blob.
:param bool validate_content:
If set to true, validates an MD5 hash for each retrieved portion of
the blob. This is primarily valuable for detecting bitflips on the wire
if using http instead of https as https (the default) will already
validate. Note that the service will only return transactional MD5s
for chunks 4MB or less so the first get request will be of size
self.MAX_CHUNK_GET_SIZE instead of self.MAX_SINGLE_GET_SIZE. If
self.MAX_CHUNK_GET_SIZE was set to greater than 4MB an error will be
thrown. As computing the MD5 takes processing time and more requests
will need to be done due to the reduced chunk size there may be some
increase in latency.
:param progress_callback:
Callback for progress with signature function(current, total)
where current is the number of bytes transfered so far, and total is
the size of the blob if known.
:type progress_callback: func(current, total)
:param int max_connections:
If set to 2 or greater, an initial get will be done for the first
self.MAX_SINGLE_GET_SIZE bytes of the blob. If this is the entire blob,
the method returns at this point. If it is not, it will download the
remaining data parallel using the number of threads equal to
max_connections. Each chunk will be of size self.MAX_CHUNK_GET_SIZE.
If set to 1, a single large get request will be done. This is not
generally recommended but available if very few threads should be
used, network requests are very expensive, or a non-seekable stream
prevents parallel download. This may also be useful if many blobs are
expected to be empty as an extra request is required for empty blobs
if max_connections is greater than 1.
:param str lease_id:
Required if the blob has an active lease.
:param datetime if_modified_since:
A DateTime value. Azure expects the date value passed in to be UTC.
If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.

0 and 60 seconds. This break period is only used if it is shorter
than the time remaining on the lease. If longer, the time remaining
on the lease is used. A new lease will not be available before the
break period has expired, but the lease may be held for longer than
the break period. If this header does not appear with a break
operation, a fixed-duration lease breaks after the remaining lease
period elapses, and an infinite lease breaks immediately.

Copies a blob asynchronously. This operation returns a copy operation
properties object, including a copy ID you can use to check or abort the
copy operation. The Blob service copies blobs on a best-effort basis.
The source blob for a copy operation may be a block blob, an append blob,
or a page blob. If the destination blob already exists, it must be of the
same blob type as the source blob. Any existing destination blob will be
overwritten. The destination blob cannot be modified while a copy operation
is in progress.
When copying from a page blob, the Blob service creates a destination page
blob of the source blob's length, initially containing all zeroes. Then
the source page ranges are enumerated, and non-empty ranges are copied.
For a block blob or an append blob, the Blob service creates a committed
blob of zero length before returning from this operation. When copying
from a block blob, all committed blocks and their block IDs are copied.
Uncommitted blocks are not copied. At the end of the copy operation, the
destination blob will have the same committed block count as the source.
When copying from an append blob, all committed blocks are copied. At the
end of the copy operation, the destination blob will have the same committed
block count as the source.
For all blob types, you can call get_blob_properties on the destination
blob to check the status of the copy operation. The final blob will be
committed when the copy completes.
:param str container_name:
Name of the destination container. The container must exist.
:param str blob_name:

A URL of up to 2 KB in length that specifies an Azure file or blob.
The value should be URL-encoded as it would appear in a request URI.
If the source is in another account, the source must either be public
or must be authenticated via a shared access signature. If the source
is public, no authentication is required.
Examples:
https://myaccount.blob.core.windows.net/mycontainer/myblob

'''
Block blobs let you upload large blobs efficiently. Block blobs are comprised
of blocks, each of which is identified by a block ID. You create or modify a
block blob by writing a set of blocks and committing them by their block IDs.
Each block can be a different size, up to a maximum of 100 MB, and a block blob
can include up to 50,000 blocks. The maximum size of a block blob is therefore
approximately 4.75 TB (100 MB X 50,000 blocks). If you are writing a block
blob that is no more than 64 MB in size, you can upload it in its entirety with
a single write operation; see create_blob_from_bytes.
:ivar int MAX_SINGLE_PUT_SIZE:
The largest size upload supported in a single put call. This is used by
the create_blob_from_* methods if the content length is known and is less
than this value.
:ivar int MAX_BLOCK_SIZE:
The size of the blocks put by create_blob_from_* methods if the content
length is unknown or is larger than MAX_SINGLE_PUT_SIZE. Smaller blocks
may be put. The maximum block size the service supports is 100MB.
:ivar int MIN_LARGE_BLOCK_UPLOAD_THRESHOLD:
The minimum block size at which the the memory-optimized, block upload
algorithm is considered. This algorithm is only applicable to the create_blob_from_file and
create_blob_from_stream methods and will prevent the full buffering of blocks.
In addition to the block size, ContentMD5 validation and Encryption must be disabled as
these options require the blocks to be buffered.

If True, this will force usage of the original full block buffering upload path.
By default, this value is False and will employ a memory-efficient,
streaming upload algorithm under the following conditions:
The provided stream is seekable, 'require_encryption' is False, and
MAX_BLOCK_SIZE >= MIN_LARGE_BLOCK_UPLOAD_THRESHOLD.
One should consider the drawbacks of using this approach. In order to achieve
memory-efficiency, a IOBase stream or file-like object is segmented into logical blocks
using a SubStream wrapper. In order to read the correct data, each SubStream must acquire
a lock so that it can safely seek to the right position on the shared, underlying stream.
If max_connections > 1, the concurrency will result in a considerable amount of seeking on
the underlying stream. For the most common inputs such as a file-like stream object, seeking
is an inexpensive operation and this is not much of a concern. However, for other variants of streams
this may not be the case. The trade-off for memory-efficiency must be weighed against the cost of seeking
with your input stream.
The SubStream class will attempt to buffer up to 4 MB internally to reduce the amount of
seek and read calls to the underlying stream. This is particularly beneficial when uploading larger blocks.

asynchronous, best-effort operation, or a synchronous operation.
The source must be a block blob if requires_sync is true. Any existing
destination blob will be overwritten. The destination blob cannot be
modified while a copy operation is in progress.
When copying from a block blob, all committed blocks and their block IDs are
copied. Uncommitted blocks are not copied. At the end of the copy operation,
the destination blob will have the same committed block count as the source.
You can call get_blob_properties on the destination blob to check the status

A URL of up to 2 KB in length that specifies an Azure file or blob.
The value should be URL-encoded as it would appear in a request URI.
If the source is in another account, the source must either be public
or must be authenticated via a shared access signature. If the source
is public, no authentication is required.

Copies a blob asynchronously. This operation returns a copy operation
properties object, including a copy ID you can use to check or abort the
copy operation. The Blob service copies blobs on a best-effort basis.
The source blob for a copy operation must be a page blob. If the destination
blob already exists, it must be of the same blob type as the source blob.
Any existing destination blob will be overwritten.
The destination blob cannot be modified while a copy operation is in progress.
When copying from a page blob, the Blob service creates a destination page
blob of the source blob's length, initially containing all zeroes. Then
the source page ranges are enumerated, and non-empty ranges are copied.
If the tier on the source blob is larger than the tier being passed to this
copy operation or if the size of the blob exceeds the tier being passed to
this copy operation then the operation will fail.
You can call get_blob_properties on the destination
blob to check the status of the copy operation. The final blob will be
committed when the copy completes.
:param str container_name:
Name of the destination container. The container must exist.
:param str blob_name:
Name of the destination blob. If the destination blob exists, it will
be overwritten. Otherwise, it will be created.
:param str copy_source:
A URL of up to 2 KB in length that specifies an Azure file or blob.
The value should be URL-encoded as it would appear in a request URI.
If the source is in another account, the source must either be public
or must be authenticated via a shared access signature. If the source
is public, no authentication is required.
Examples:
https://myaccount.blob.core.windows.net/mycontainer/myblob
https://myaccount.blob.core.windows.net/mycontainer/myblob?snapshot=
https://otheraccount.blob.core.windows.net/mycontainer/myblob?sastoken
:param metadata:
Name-value pairs associated with the blob as metadata. If no name-value
pairs are specified, the operation will copy the metadata from the
source blob or file to the destination blob. If one or more name-value
pairs are specified, the destination blob is created with the specified
metadata, and metadata is not copied from the source blob or file.
:type metadata: dict(str, str).
:param datetime source_if_modified_since:
A DateTime value. Azure expects the date value passed in to be UTC.
If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.
Specify this conditional header to copy the blob only if the source
blob has been modified since the specified date/time.
:param datetime source_if_unmodified_since:
A DateTime value. Azure expects the date value passed in to be UTC.
If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.
Specify this conditional header to copy the blob only if the source blob
has not been modified since the specified date/time.
:param ETag source_if_match:
An ETag value, or the wildcard character (*). Specify this conditional
header to copy the source blob only if its ETag matches the value
specified. If the ETag values do not match, the Blob service returns
status code 412 (Precondition Failed). This header cannot be specified
if the source is an Azure File.
:param ETag source_if_none_match:
An ETag value, or the wildcard character (*). Specify this conditional
header to copy the blob only if its ETag does not match the value
specified. If the values are identical, the Blob service returns status
code 412 (Precondition Failed). This header cannot be specified if the
source is an Azure File.
:param datetime destination_if_modified_since:
A DateTime value. Azure expects the date value passed in to be UTC.
If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.
Specify this conditional header to copy the blob only
if the destination blob has been modified since the specified date/time.
If the destination blob has not been modified, the Blob service returns
status code 412 (Precondition Failed).
:param datetime destination_if_unmodified_since:
A DateTime value. Azure expects the date value passed in to be UTC.
If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.
Specify this conditional header to copy the blob only
if the destination blob has not been modified since the specified
date/time. If the destination blob has been modified, the Blob service
returns status code 412 (Precondition Failed).
:param ETag destination_if_match:
An ETag value, or the wildcard character (*). Specify an ETag value for
this conditional header to copy the blob only if the specified ETag value
matches the ETag value for an existing destination blob. If the ETag for
the destination blob does not match the ETag specified for If-Match, the
Blob service returns status code 412 (Precondition Failed).
:param ETag destination_if_none_match:
An ETag value, or the wildcard character (*). Specify an ETag value for
this conditional header to copy the blob only if the specified ETag value
does not match the ETag value for the destination blob. Specify the wildcard
character (*) to perform the operation only if the destination blob does not
exist. If the specified condition isn't met, the Blob service returns status
code 412 (Precondition Failed).
:param str destination_lease_id:
The lease ID specified for this header must match the lease ID of the
destination blob. If the request does not include the lease ID or it is not
valid, the operation fails with status code 412 (Precondition Failed).
:param str source_lease_id:
Specify this to perform the Copy Blob operation only if
the lease ID given matches the active lease ID of the source blob.
:param int timeout:
The timeout parameter is expressed in seconds.
:param PageBlobTier premium_page_blob_tier:
A page blob tier value to set on the destination blob. The tier correlates to
the size of the blob and number of allowed IOPS. This is only applicable to
page blobs on premium storage accounts.
If the tier on the source blob is larger than the tier being passed to this
copy operation or if the size of the blob exceeds the tier being passed to
this copy operation then the operation will fail.
:return: Copy operation properties such as status, source, and ID.

:ivar function(context) retry:
A function which determines whether to retry. Takes as a parameter a
:class:`~azure.storage.common.models.RetryContext` object. Returns the number
of seconds to wait before retrying the request, or None to indicate not
to retry.
:ivar ~azure.storage.common.models.LocationMode location_mode:
The host location to use to make requests. Defaults to LocationMode.PRIMARY.
Note that this setting only applies to RA-GRS accounts as other account
types do not allow reading from secondary. If the location_mode is set to
LocationMode.SECONDARY, read requests will be sent to the secondary endpoint.
Write requests will continue to be sent to primary.
:ivar str protocol:
The protocol to use for requests. Defaults to https.
:ivar requests.Session request_session:
The session object to use for http requests.
:ivar function(request) request_callback:
A function called immediately before each request is sent. This function
takes as a parameter the request object and returns nothing. It may be
used to added custom headers or log request data.
:ivar function() response_callback:
A function called immediately after each response is received. This
function takes as a parameter the response object and returns nothing.
It may be used to log response data.
:ivar function() retry_callback:
A function called immediately after retry evaluation is performed. This
function takes as a parameter the retry context object and returns nothing.
It may be used to detect retries and log context information.

The Server Message Block (SMB) protocol is the preferred file share protocol

leverage the availability and scalability of Azure's Cloud Infrastructure as

The Azure File service also offers a compelling alternative to traditional
Direct Attached Storage (DAS) and Storage Area Network (SAN) solutions, which
are often complex and expensive to install, configure, and operate.

This is the main class managing queue resources.
The Queue service stores messages. A queue can contain an unlimited number of
messages, each of which can be up to 64KB in size. Messages are generally added
to the end of the queue and retrieved from the front of the queue, although
first in, first out (FIFO) behavior is not guaranteed.
:ivar function(data) encode_function:
A function used to encode queue messages. Takes as
a parameter the data passed to the put_message API and returns the encoded
message. Defaults to take text and xml encode, but bytes and other
encodings can be used. For example, base64 may be preferable for developing
across multiple Azure Storage libraries in different languages. See the
:class:`~azure.storage.queue.models.QueueMessageFormat` for xml, base64 and
no encoding methods as well as binary equivalents.
:ivar function(data) decode_function:
A function used to encode decode messages. Takes as
a parameter the data returned by the get_messages and peek_messages APIs and
returns the decoded message. Defaults to return text and xml decode, but
bytes and other decodings can be used. For example, base64 may be preferable
for developing across multiple Azure Storage libraries in different languages.
See the :class:`~azure.storage.queue.models.QueueMessageFormat` for xml, base64

For methods requiring decryption, either the key_encryption_key OR the resolver must be provided.
If both are provided, the resolver will take precedence.
Must implement the following methods for APIs requiring encryption:
wrap_key(key)--wraps the specified key (bytes) using an algorithm of the user's choice. Returns the encrypted key as bytes.
get_key_wrap_algorithm()--returns the algorithm used to wrap the specified symmetric key.
get_kid()--returns a string key id for this key-encryption-key.
Must implement the following methods for APIs requiring decryption:
unwrap_key(key, algorithm)--returns the unwrapped form of the specified symmetric key using the string-specified algorithm.
get_kid()--returns a string key id for this key-encryption-key.
:ivar function key_resolver_function(kid):
A function to resolve keys optionally provided by the user. If provided, will be used to decrypt in supported methods.
For methods requiring decryption, either the key_encryption_key OR
the resolver must be provided. If both are provided, the resolver will take precedence.
It uses the kid string to return a key-encryption-key implementing the interface defined above.
:ivar bool require_encryption:
A flag that may be set to ensure that all messages successfully uploaded to the queue and all those downloaded and
successfully read from the queue are/were encrypted while on the server. If this flag is set, all required
parameters for encryption/decryption must be provided. See the above comments on the key_encryption_key and resolver.

"""Creates a new blob from a data source with automatic chunking.
:param data: The blob data to upload.
:param ~azure.storage.blob.BlobType blob_type: The type of the blob. This can be
either BlockBlob, PageBlob or AppendBlob. The default value is BlockBlob.
:param int length:
Number of bytes to read from the stream. This is optional, but
should be supplied for optimal performance.
:param metadata:
Name-value pairs associated with the blob as metadata.
:type metadata: dict(str, str)
:keyword bool overwrite: Whether the blob to be uploaded should overwrite the current data.
If True, upload_blob will overwrite the existing data. If set to False, the
operation will fail with ResourceExistsError. The exception to the above is with Append
blob types: if set to False and the data already exists, an error will not be raised
and the data will be appended to the existing blob. If set overwrite=True, then the existing
append blob will be deleted, and a new one created. Defaults to False.
:keyword ~azure.storage.blob.ContentSettings content_settings:
ContentSettings object used to set blob properties. Used to set content type, encoding,
language, disposition, md5, and cache control.
:keyword bool validate_content:
If true, calculates an MD5 hash for each chunk of the blob. The storage
service checks the hash of the content that has arrived with the hash
that was sent. This is primarily valuable for detecting bitflips on
the wire if using http instead of https, as https (the default), will
already validate. Note that this MD5 hash is not stored with the
blob. Also note that if enabled, the memory-efficient upload algorithm
will not be used because computing the MD5 hash requires buffering
entire blocks, and doing so defeats the purpose of the memory-efficient algorithm.
:keyword lease:
Required if the blob has an active lease. If specified, upload_blob only succeeds if the
blob's lease is active and matches this ID. Value can be a BlobLeaseClient object
or the lease ID as a string.
:paramtype lease: ~azure.storage.blob.BlobLeaseClient or str
:keyword ~datetime.datetime if_modified_since:
A DateTime value. Azure expects the date value passed in to be UTC.
If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.
Specify this header to perform the operation only
if the resource has been modified since the specified time.
:keyword ~datetime.datetime if_unmodified_since:
A DateTime value. Azure expects the date value passed in to be UTC.
If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.
Specify this header to perform the operation only if
the resource has not been modified since the specified date/time.
:keyword str etag:
An ETag value, or the wildcard character (*). Used to check if the resource has changed,
and act according to the condition specified by the `match_condition` parameter.
:keyword ~azure.core.MatchConditions match_condition:
The match condition to use upon the etag.
:keyword ~azure.storage.blob.PremiumPageBlobTier premium_page_blob_tier:
A page blob tier value to set the blob to. The tier correlates to the size of the
blob and number of allowed IOPS. This is only applicable to page blobs on
premium storage accounts.
:keyword ~azure.storage.blob.StandardBlobTier standard_blob_tier:
A standard blob tier value to set the blob to. For this version of the library,
this is only applicable to block blobs on standard storage accounts.
:keyword int maxsize_condition:
Optional conditional header. The max length in bytes permitted for
the append blob. If the Append Block operation would cause the blob
to exceed that limit or if the blob size is already greater than the
value specified in this header, the request will fail with
MaxBlobSizeConditionNotMet error (HTTP status code 412 - Precondition Failed).
:keyword int max_concurrency:
Maximum number of parallel connections to use when the blob size exceeds
64MB.
:keyword ~azure.storage.blob.CustomerProvidedEncryptionKey cpk:
Encrypts the data on the service-side with the given key.
Use of customer-provided keys must be done over HTTPS.
As the encryption key itself is provided in the request,
a secure connection must be established to transfer the key.
:keyword str encryption_scope:
A predefined encryption scope used to encrypt the data on the service. An encryption
scope can be created using the Management API and referenced here by name. If a default
encryption scope has been defined at the container, this value will override it if the
container-level scope is configured to allow overrides. Otherwise an error will be raised.
.. versionadded:: 12.2.0
:keyword str encoding:
Defaults to UTF-8.

The timeout parameter is expressed in seconds. This method may make
multiple calls to the Azure service and the timeout will apply to
each call individually.

"""Copies a blob asynchronously.
This operation returns a copy operation
object that can be used to wait on the completion of the operation,
as well as check status or abort the copy operation.
The Blob service copies blobs on a best-effort basis.
The source blob for a copy operation may be a block blob, an append blob,
or a page blob. If the destination blob already exists, it must be of the
same blob type as the source blob. Any existing destination blob will be
overwritten. The destination blob cannot be modified while a copy operation
is in progress.
When copying from a page blob, the Blob service creates a destination page
blob of the source blob's length, initially containing all zeroes. Then
the source page ranges are enumerated, and non-empty ranges are copied.
For a block blob or an append blob, the Blob service creates a committed
blob of zero length before returning from this operation. When copying
from a block blob, all committed blocks and their block IDs are copied.
Uncommitted blocks are not copied. At the end of the copy operation, the
destination blob will have the same committed block count as the source.
When copying from an append blob, all committed blocks are copied. At the
end of the copy operation, the destination blob will have the same committed
block count as the source.
For all blob types, you can call status() on the returned polling object
to check the status of the copy operation, or wait() to block until the
operation is complete. The final blob will be committed when the copy completes.
:param str source_url:
A URL of up to 2 KB in length that specifies a file or blob.
The value should be URL-encoded as it would appear in a request URI.
If the source is in another account, the source must either be public
or must be authenticated via a shared access signature. If the source
is public, no authentication is required.
Examples:
https://myaccount.blob.core.windows.net/mycontainer/myblob
https://myaccount.blob.core.windows.net/mycontainer/myblob?snapshot=
https://otheraccount.blob.core.windows.net/mycontainer/myblob?sastoken
:param metadata:
Name-value pairs associated with the blob as metadata. If no name-value
pairs are specified, the operation will copy the metadata from the
source blob or file to the destination blob. If one or more name-value
pairs are specified, the destination blob is created with the specified
metadata, and metadata is not copied from the source blob or file.
:type metadata: dict(str, str)
:param bool incremental_copy:
Copies the snapshot of the source page blob to a destination page blob.
The snapshot is copied such that only the differential changes between
the previously copied snapshot are transferred to the destination.
The copied snapshots are complete copies of the original snapshot and
can be read or copied from as usual. Defaults to False.

Optional conditional header. The max length in bytes permitted for
the append blob. If the Append Block operation would cause the blob
to exceed that limit or if the blob size is already greater than the
value specified in this header, the request will fail with
MaxBlobSizeConditionNotMet error (HTTP status code 412 - Precondition Failed).
:keyword int appendpos_condition:
Optional conditional header, used only for the Append Block operation.
A number indicating the byte offset to compare. Append Block will
succeed only if the append position is equal to this number. If it
is not, the request will fail with the

"""Creates a new blob from a data source with automatic chunking.
:param name: The blob with which to interact. If specified, this value will override
a blob value specified in the blob URL.
:type name: str or ~azure.storage.blob.BlobProperties
:param data: The blob data to upload.
:param ~azure.storage.blob.BlobType blob_type: The type of the blob. This can be
either BlockBlob, PageBlob or AppendBlob. The default value is BlockBlob.
:param int length:
Number of bytes to read from the stream. This is optional, but
should be supplied for optimal performance.
:param metadata:
Name-value pairs associated with the blob as metadata.
:type metadata: dict(str, str)
:keyword bool overwrite: Whether the blob to be uploaded should overwrite the current data.
If True, upload_blob will overwrite the existing data. If set to False, the
operation will fail with ResourceExistsError. The exception to the above is with Append
blob types: if set to False and the data already exists, an error will not be raised
and the data will be appended to the existing blob. If set overwrite=True, then the existing
append blob will be deleted, and a new one created. Defaults to False.
:keyword ~azure.storage.blob.ContentSettings content_settings:
ContentSettings object used to set blob properties. Used to set content type, encoding,
language, disposition, md5, and cache control.
:keyword bool validate_content:
If true, calculates an MD5 hash for each chunk of the blob. The storage
service checks the hash of the content that has arrived with the hash
that was sent. This is primarily valuable for detecting bitflips on
the wire if using http instead of https, as https (the default), will
already validate. Note that this MD5 hash is not stored with the
blob. Also note that if enabled, the memory-efficient upload algorithm
will not be used, because computing the MD5 hash requires buffering
entire blocks, and doing so defeats the purpose of the memory-efficient algorithm.
:keyword lease:
Required if the container has an active lease. Value can be a BlobLeaseClient object
or the lease ID as a string.
:paramtype lease: ~azure.storage.blob.BlobLeaseClient or str
:keyword ~datetime.datetime if_modified_since:
A DateTime value. Azure expects the date value passed in to be UTC.
If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.
Specify this header to perform the operation only
if the resource has been modified since the specified time.
:keyword ~datetime.datetime if_unmodified_since:
A DateTime value. Azure expects the date value passed in to be UTC.
If timezone is included, any non-UTC datetimes will be converted to UTC.
If a date is passed in without timezone info, it is assumed to be UTC.
Specify this header to perform the operation only if
the resource has not been modified since the specified date/time.
:keyword str etag:
An ETag value, or the wildcard character (*). Used to check if the resource has changed,
and act according to the condition specified by the `match_condition` parameter.
:keyword ~azure.core.MatchConditions match_condition:
The match condition to use upon the etag.
:keyword int timeout:
The timeout parameter is expressed in seconds. This method may make
multiple calls to the Azure service and the timeout will apply to
each call individually.
:keyword ~azure.storage.blob.PremiumPageBlobTier premium_page_blob_tier:
A page blob tier value to set the blob to. The tier correlates to the size of the
blob and number of allowed IOPS. This is only applicable to page blobs on
premium storage accounts.
:keyword ~azure.storage.blob.StandardBlobTier standard_blob_tier:
A standard blob tier value to set the blob to. For this version of the library,
this is only applicable to block blobs on standard storage accounts.
:keyword int maxsize_condition:
Optional conditional header. The max length in bytes permitted for
the append blob. If the Append Block operation would cause the blob
to exceed that limit or if the blob size is already greater than the
value specified in this header, the request will fail with
MaxBlobSizeConditionNotMet error (HTTP status code 412 - Precondition Failed).
:keyword int max_concurrency:
Maximum number of parallel connections to use when the blob size exceeds
64MB.
:keyword ~azure.storage.blob.CustomerProvidedEncryptionKey cpk:
Encrypts the data on the service-side with the given key.
Use of customer-provided keys must be done over HTTPS.
As the encryption key itself is provided in the request,
a secure connection must be established to transfer the key.
:keyword str encryption_scope:
A predefined encryption scope used to encrypt the data on the service. An encryption
scope can be created using the Management API and referenced here by name. If a default
encryption scope has been defined at the container, this value will override it if the
container-level scope is configured to allow overrides. Otherwise an error will be raised.

:param posix_permissions: Optional and only valid if Hierarchical
Namespace is enabled for the account. Sets POSIX access permissions
for the file owner, the file owning group, and others. Each class may
be granted read, write, or execute permission. The sticky bit is also
supported. Both symbolic (rwxrw-rw-) and 4-digit octal notation (e.g.
0766) are supported.

for the account. This umask restricts permission settings for file and
directory, and will only be applied when default Acl does not exist in
parent directory. If the umask bit has set, it means that the
corresponding permission will be disabled. Otherwise the corresponding
permission will be determined by the permission. A 4-digit octal
notation (e.g. 0022) is supported here. If no umask was specified, a
default umask - 0027 will be used.

operation will copy the metadata from the source blob or file to the
destination blob. If one or more name-value pairs are specified, the
destination blob is created with the specified metadata, and metadata
is not copied from the source blob or file. Note that beginning with

"""The Commit Block List operation writes a blob by specifying the list of
block IDs that make up the blob. In order to be written as part of a
blob, a block must have been successfully written to the server in a
prior Put Block operation. You can call Put Block List to update a blob
by uploading only those blocks that have changed, then committing the
new and existing blocks together. You can do this by specifying whether
to commit a block from the committed block list or from the uncommitted
block list, or to commit the most recently uploaded version of the
block, whichever list it may belong to.

The permissions associated with the shared access signature. The
user is restricted to operations allowed by the permissions.
Required unless an id is given referencing a stored access policy

The time at which the shared access signature becomes invalid.
Required unless an id is given referencing a stored access policy

convert values to UTC. If a date is passed in without timezone info, it
is assumed to be UTC.

:param str ip:
Specifies an IP address or a range of IP addresses from which to accept requests.
If the IP address from which the request originates does not match the IP address
or address range specified on the SAS token, the request is not authenticated.
For example, specifying sip=168.1.5.65 or sip=168.1.5.60-168.1.5.70 on the SAS
restricts the request to those IP addresses.

Specifies the protocol permitted for a request made. The default value
is https,http. See :class:`~azure.storage.common.models.Protocol` for possible values.

"""Copies a blob asynchronously.
This operation returns a copy operation
object that can be used to wait on the completion of the operation,
as well as check status or abort the copy operation.
The Blob service copies blobs on a best-effort basis.
The source blob for a copy operation may be a block blob, an append blob,
or a page blob. If the destination blob already exists, it must be of the
same blob type as the source blob. Any existing destination blob will be
overwritten. The destination blob cannot be modified while a copy operation
is in progress.
When copying from a page blob, the Blob service creates a destination page
blob of the source blob's length, initially containing all zeroes. Then
the source page ranges are enumerated, and non-empty ranges are copied.
For a block blob or an append blob, the Blob service creates a committed
blob of zero length before returning from this operation. When copying
from a block blob, all committed blocks and their block IDs are copied.
Uncommitted blocks are not copied. At the end of the copy operation, the
destination blob will have the same committed block count as the source.
When copying from an append blob, all committed blocks are copied. At the
end of the copy operation, the destination blob will have the same committed
block count as the source.
For all blob types, you can call status() on the returned polling object
to check the status of the copy operation, or wait() to block until the
operation is complete. The final blob will be committed when the copy completes.
:param str source_url:
A URL of up to 2 KB in length that specifies a file or blob.
The value should be URL-encoded as it would appear in a request URI.
If the source is in another account, the source must either be public

is public, no authentication is required.
Examples:
https://myaccount.blob.core.windows.net/mycontainer/myblob

https://otheraccount.blob.core.windows.net/mycontainer/myblob?sastoken

the wire if using http instead of https, as https (the default), will
already validate. Note that this MD5 hash is not stored with the
blob. Also note that if enabled, the memory-efficient upload algorithm
will not be used because computing the MD5 hash requires buffering
entire blocks, and doing so defeats the purpose of the memory-efficient algorithm.

Specify this header to perform the operation only if
the resource has not been modified since the specified date/time.

An ETag value, or the wildcard character (*). Used to check if the resource has changed,
and act according to the condition specified by the `match_condition` parameter.
:keyword ~azure.core.MatchConditions match_condition:
The match condition to use upon the etag.
:keyword ~azure.storage.blob.CustomerProvidedEncryptionKey cpk:
Encrypts the data on the service-side with the given key.
Use of customer-provided keys must be done over HTTPS.
As the encryption key itself is provided in the request,
a secure connection must be established to transfer the key.
:keyword int max_concurrency:
The number of parallel connections with which to download.
:keyword str encoding:
Encoding to decode the downloaded bytes. Default is None, i.e. no decoding.
:keyword int timeout:
The timeout parameter is expressed in seconds. This method may make
multiple calls to the Azure service and the timeout will apply to
each call individually.

the wire if using http instead of https as https (the default) will
already validate. Note that this MD5 hash is not stored with the

"""Copies a blob from the given URL.
This operation returns a dictionary containing `copy_status` and `copy_id`,
which can be used to check the status of or abort the copy operation.
`copy_status` will be 'success' if the copy completed synchronously or
'pending' if the copy has been started asynchronously. For asynchronous copies,
the status can be checked by polling the :func:`get_blob_properties` method and
checking the copy status. Set `requires_sync` to True to force the copy to be synchronous.
The Blob service copies blobs on a best-effort basis.
The source blob for a copy operation may be a block blob, an append blob,
or a page blob. If the destination blob already exists, it must be of the
same blob type as the source blob. Any existing destination blob will be
overwritten. The destination blob cannot be modified while a copy operation
is in progress.
When copying from a page blob, the Blob service creates a destination page
blob of the source blob's length, initially containing all zeroes. Then
the source page ranges are enumerated, and non-empty ranges are copied.
For a block blob or an append blob, the Blob service creates a committed
blob of zero length before returning from this operation. When copying
from a block blob, all committed blocks and their block IDs are copied.
Uncommitted blocks are not copied. At the end of the copy operation, the
destination blob will have the same committed block count as the source.
When copying from an append blob, all committed blocks are copied. At the
end of the copy operation, the destination blob will have the same committed
block count as the source.
:param str source_url:
A URL of up to 2 KB in length that specifies a file or blob.
The value should be URL-encoded as it would appear in a request URI.
If the source is in another account, the source must either be public
or must be authenticated via a shared access signature. If the source
is public, no authentication is required.
Examples:
https://myaccount.blob.core.windows.net/mycontainer/myblob
https://myaccount.blob.core.windows.net/mycontainer/myblob?snapshot=
https://otheraccount.blob.core.windows.net/mycontainer/myblob?sastoken
:param metadata:
Name-value pairs associated with the blob as metadata. If no name-value
pairs are specified, the operation will copy the metadata from the
source blob or file to the destination blob. If one or more name-value
pairs are specified, the destination blob is created with the specified
metadata, and metadata is not copied from the source blob or file.
:type metadata: dict(str, str)
:param bool incremental_copy:
Copies the snapshot of the source page blob to a destination page blob.
The snapshot is copied such that only the differential changes between
the previously copied snapshot are transferred to the destination.
The copied snapshots are complete copies of the original snapshot and
can be read or copied from as usual. Defaults to False.
:keyword tags:
Name-value pairs associated with the blob as tag. Tags are case-sensitive.
The tag set may contain at most 10 tags. Tag keys must be between 1 and 128 characters,
and tag values must be between 0 and 256 characters.
Valid tag key and value characters include: lowercase and uppercase letters, digits (0-9),
space (` `), plus (+), minus (-), period (.), solidus (/), colon (:), equals (=), underscore (_).
The (case-sensitive) literal "COPY" can instead be passed to copy tags from the source blob.

permanently removed from the storage account. If the storage account's soft delete feature is
enabled, then, when a blob is deleted, it is marked for deletion and becomes inaccessible
immediately. However, the blob service retains the blob or snapshot for the number of days
specified by the DeleteRetentionPolicy section of [Storage service properties]
(Set-Blob-Service-Properties.md). After the specified number of days has passed, the blob's
data is permanently removed from the storage account. Note that you continue to be charged for
the soft-deleted blob's storage until it is permanently removed. Use the List Blobs API and
specify the "include=deleted" query parameter to discover which blobs and snapshots have been
soft deleted. You can then use the Undelete Blob API to restore a soft-deleted blob. All other
operations on a soft-deleted blob or snapshot causes the service to return an HTTP status code
of 404 (ResourceNotFound).

specifies the blob snapshot to retrieve. For more information on working with blob snapshots,
see :code:`Creating
a Snapshot of a Blob.`. Default value is None.
:type snapshot: str
:param timeout: The timeout parameter is expressed in seconds. For more information, see
:code:`Setting
Timeouts for Blob Service Operations.`. Default value is None.
:type timeout: int
:param prevsnapshot: Optional in version 2015-07-08 and newer. The prevsnapshot parameter is a
DateTime value that specifies that the response will contain only pages that were changed
between target blob and previous snapshot. Changed pages include both updated and cleared
pages. The target blob may be a snapshot, as long as the snapshot specified by prevsnapshot is
the older of the two. Note that incremental snapshots are currently supported only for blobs
created on or after January 1, 2016. Default value is None.
:type prevsnapshot: str
:param prev_snapshot_url: Optional. This header is only supported in service versions
2019-04-19 and after and specifies the URL of a previous snapshot of the target blob. The
response will only contain pages that were changed between the target blob and its previous
snapshot. Default value is None.

limit that is recorded in the analytics logs when storage analytics logging is enabled. Default
value is None.

:param marker: A string value that identifies the portion of the list of containers to be
returned with the next listing operation. The operation returns the NextMarker value within the
response body if the listing operation did not return all containers remaining to be listed
with the current page. The NextMarker value can be used as the value for the marker parameter
in a subsequent call to request the next page of list items. The marker value is opaque to the
client. Default value is None.
:type marker: str
:param maxresults: Specifies the maximum number of containers to return. If the request does
not specify maxresults, or specifies a value greater than 5000, the server will return up to
5000 items. Note that if the listing operation crosses a partition boundary, then the service
will return a continuation token for retrieving the remainder of the results. For this reason,
it is possible that the service will return fewer results than specified by maxresults, or than
the default of 5000. Default value is None.

not specify maxresults, or specifies a value greater than 5000, the server will return up to
5000 items. Note that if the listing operation crosses a partition boundary, then the service
will return a continuation token for retrieving the remainder of the results. For this reason,
it is possible that the service will return fewer results than specified by maxresults, or than
the default of 5000. Default value is None.

specify the "include=deleted" query parameter to discover which blobs and snapshots have been
soft deleted. You can then use the Undelete Blob API to restore a soft-deleted blob. All other
operations on a soft-deleted blob or snapshot causes the service to return an HTTP status code

:param marker: A string value that identifies the portion of the list of containers to be
returned with the next listing operation. The operation returns the NextMarker value within the
response body if the listing operation did not return all containers remaining to be listed
with the current page. The NextMarker value can be used as the value for the marker parameter
in a subsequent call to request the next page of list items. The marker value is opaque to the
client. Default value is None.
:type marker: str
:param maxresults: Specifies the maximum number of containers to return. If the request does
not specify maxresults, or specifies a value greater than 5000, the server will return up to
5000 items. Note that if the listing operation crosses a partition boundary, then the service
will return a continuation token for retrieving the remainder of the results. For this reason,
it is possible that the service will return fewer results than specified by maxresults, or than
the default of 5000. Default value is None.
:type maxresults: int
:param include: Include this parameter to specify one or more datasets to include in the
response. Default value is None.
:type include: list[str or ~azure.storage.blob.models.ListBlobsIncludeItem]
:param timeout: The timeout parameter is expressed in seconds. For more information, see
:code:`Setting
Timeouts for Blob Service Operations.`. Default value is None.
:type timeout: int
:param request_id_parameter: Provides a client-generated, opaque value with a 1 KB character
limit that is recorded in the analytics logs when storage analytics logging is enabled. Default
value is None.
:type request_id_parameter: str
:keyword restype: restype. Default value is "container". Note that overriding this default
value may result in unsupported behavior.
:paramtype restype: str

specify all of these parameters within the stored access policy, and omit
them from the URL for the Shared Access Signature. Doing so permits you to
modify the associated signature's behavior at any time, as well as to revoke
it. Or you can specify one or more of the access policy parameters within
the stored access policy, and the others on the URL. Finally, you can
specify all of the parameters on the URL. In this case, you can use the
stored access policy to revoke the signature, but not to modify its behavior.
Together the Shared Access Signature and the stored access policy must
include all fields required to authenticate the signature. If any required
fields are missing, the request will fail. Likewise, if a field is specified
both in the Shared Access Signature URL and in the stored access policy, the
request will fail with status code 400 (Bad Request).
:param permission:
The permissions associated with the shared access signature. The
user is restricted to operations allowed by the permissions.
Required unless an id is given referencing a stored access policy
which contains this field. This field must be omitted if it has been
specified in an associated stored access policy.
:type permission: str or ~azure.storage.blob.ContainerSasPermissions
:param expiry:
The time at which the shared access signature becomes invalid.
Required unless an id is given referencing a stored access policy
which contains this field. This field must be omitted if it has
been specified in an associated stored access policy. Azure will always
convert values to UTC. If a date is passed in without timezone info, it
is assumed to be UTC.
:type expiry: ~datetime.datetime or str
:param start:
The time at which the shared access signature becomes valid. If
omitted, start time for this call is assumed to be the time when the
storage service receives the request. Azure will always convert values
to UTC. If a date is passed in without timezone info, it is assumed to
be UTC.

already validate. Note that this MD5 hash is not stored with the

"""Copies a blob from the given URL.
This operation returns a dictionary containing `copy_status` and `copy_id`,
which can be used to check the status of or abort the copy operation.
`copy_status` will be 'success' if the copy completed synchronously or
'pending' if the copy has been started asynchronously. For asynchronous copies,
the status can be checked by polling the :func:`get_blob_properties` method and
checking the copy status. Set `requires_sync` to True to force the copy to be synchronous.
The Blob service copies blobs on a best-effort basis.
The source blob for a copy operation may be a block blob, an append blob,
or a page blob. If the destination blob already exists, it must be of the
same blob type as the source blob. Any existing destination blob will be
overwritten. The destination blob cannot be modified while a copy operation
is in progress.
When copying from a page blob, the Blob service creates a destination page
blob of the source blob's length, initially containing all zeroes. Then
the source page ranges are enumerated, and non-empty ranges are copied.
For a block blob or an append blob, the Blob service creates a committed
blob of zero length before returning from this operation. When copying
from a block blob, all committed blocks and their block IDs are copied.
Uncommitted blocks are not copied. At the end of the copy operation, the
destination blob will have the same committed block count as the source.
When copying from an append blob, all committed blocks are copied. At the
end of the copy operation, the destination blob will have the same committed
block count as the source.

A URL of up to 2 KB in length that specifies a file or blob.
The value should be URL-encoded as it would appear in a request URI.

is public, no authentication is required.
Examples:
https://myaccount.blob.core.windows.net/mycontainer/myblob

Copies the snapshot of the source page blob to a destination page blob.
The snapshot is copied such that only the differential changes between
the previously copied snapshot are transferred to the destination.

Name-value pairs associated with the blob as tag. Tags are case-sensitive.
The tag set may contain at most 10 tags. Tag keys must be between 1 and 128 characters,

Valid tag key and value characters include: lowercase and uppercase letters, digits (0-9),

This client provides operations to retrieve and configure the account properties
as well as list, create and delete containers within the account.
For operations relating to a specific container or blob, clients for those entities
can also be retrieved using the `get_client` functions.
:param str account_url:
The URL to the blob storage account. Any other entities included
in the URL path (e.g. container or blob) will be discarded. This URL can be optionally
authenticated with a SAS token.
:param credential:
The credentials with which to authenticate. This is optional if the
account URL already has a SAS token. The value can be a SAS token string,
an instance of a AzureSasCredential or AzureNamedKeyCredential from azure.core.credentials,
an account shared access key, or an instance of a TokenCredentials class from azure.identity.
If the resource URI already contains a SAS token, this will be ignored in favor of an explicit credential
- except in the case of AzureSasCredential, where the conflicting SAS tokens will raise a ValueError.
If using an instance of AzureNamedKeyCredential, "name" should be the storage account name, and "key"
should be the storage account key.

The Storage API version to use for requests. Default value is the most recent service version that is
compatible with the current SDK. Setting to an older version may result in reduced feature compatibility.

Defaults to 4*1024*1024, or 4MB.
:keyword int max_single_put_size: If the blob size is less than or equal max_single_put_size, then the blob will be
uploaded with only one http PUT request. If the blob size is larger than max_single_put_size,
the blob will be uploaded in chunks. Defaults to 64*1024*1024, or 64MB.
:keyword int min_large_block_upload_threshold: The minimum chunk size required to use the memory efficient
algorithm when uploading a block blob. Defaults to 4*1024*1024+1.
:keyword bool use_byte_buffer: Use a byte buffer for block blob uploads. Defaults to False.
:keyword int max_page_size: The maximum chunk size for uploading a page blob. Defaults to 4*1024*1024, or 4MB.
:keyword int max_single_get_size: The maximum size for a blob to be downloaded in a single call,
the exceeded part will be downloaded in chunks (could be parallel). Defaults to 32*1024*1024, or 32MB.
:keyword int max_chunk_get_size: The maximum chunk size used for downloading a blob. Defaults to 4*1024*1024,

may not yet exist.
For operations relating to a specific blob within this container, a blob client can be
retrieved using the :func:`~get_blob_client` function.
:param str account_url:
The URI to the storage account. In order to create a client given the full URI to the container,
use the :func:`from_container_url` classmethod.
:param container_name:
The name of the container for the blob.
:type container_name: str
:param credential:
The credentials with which to authenticate. This is optional if the
account URL already has a SAS token. The value can be a SAS token string,
an instance of a AzureSasCredential or AzureNamedKeyCredential from azure.core.credentials,
an account shared access key, or an instance of a TokenCredentials class from azure.identity.
If the resource URI already contains a SAS token, this will be ignored in favor of an explicit credential
- except in the case of AzureSasCredential, where the conflicting SAS tokens will raise a ValueError.
If using an instance of AzureNamedKeyCredential, "name" should be the storage account name, and "key"
should be the storage account key.

Defaults to 4*1024*1024, or 4MB.
:keyword int max_single_put_size: If the blob size is less than or equal max_single_put_size, then the blob will be
uploaded with only one http PUT request. If the blob size is larger than max_single_put_size,
the blob will be uploaded in chunks. Defaults to 64*1024*1024, or 64MB.
:keyword int min_large_block_upload_threshold: The minimum chunk size required to use the memory efficient
algorithm when uploading a block blob. Defaults to 4*1024*1024+1.
:keyword bool use_byte_buffer: Use a byte buffer for block blob uploads. Defaults to False.
:keyword int max_page_size: The maximum chunk size for uploading a page blob. Defaults to 4*1024*1024, or 4MB.
:keyword int max_single_get_size: The maximum size for a blob to be downloaded in a single call,
the exceeded part will be downloaded in chunks (could be parallel). Defaults to 32*1024*1024, or 32MB.
:keyword int max_chunk_get_size: The maximum chunk size used for downloading a blob. Defaults to 4*1024*1024,
or 4MB.

If True, upload_blob will overwrite the existing data. If set to False, the
operation will fail with ResourceExistsError. The exception to the above is with Append
blob types: if set to False and the data already exists, an error will not be raised
and the data will be appended to the existing blob. If set overwrite=True, then the existing
append blob will be deleted, and a new one created. Defaults to False.

ContentSettings object used to set blob properties. Used to set content type, encoding,
language, disposition, md5, and cache control.
:keyword bool validate_content:
If true, calculates an MD5 hash for each chunk of the blob. The storage
service checks the hash of the content that has arrived with the hash
that was sent. This is primarily valuable for detecting bitflips on
the wire if using http instead of https, as https (the default), will
already validate. Note that this MD5 hash is not stored with the

will not be used, because computing the MD5 hash requires buffering
entire blocks, and doing so defeats the purpose of the memory-efficient algorithm.

An ETag value, or the wildcard character (*). Used to check if the resource has changed,
and act according to the condition specified by the `match_condition` parameter.

A page blob tier value to set the blob to. The tier correlates to the size of the
blob and number of allowed IOPS. This is only applicable to page blobs on
premium storage accounts.
:keyword ~azure.storage.blob.StandardBlobTier standard_blob_tier:
A standard blob tier value to set the blob to. For this version of the library,
this is only applicable to block blobs on standard storage accounts.
:keyword int maxsize_condition:
Optional conditional header. The max length in bytes permitted for
the append blob. If the Append Block operation would cause the blob
to exceed that limit or if the blob size is already greater than the
value specified in this header, the request will fail with
MaxBlobSizeConditionNotMet error (HTTP status code 412 - Precondition Failed).
:keyword int max_concurrency:
Maximum number of parallel connections to use when the blob size exceeds
64MB.
:keyword ~azure.storage.blob.CustomerProvidedEncryptionKey cpk:
Encrypts the data on the service-side with the given key.
Use of customer-provided keys must be done over HTTPS.
As the encryption key itself is provided in the request,
a secure connection must be established to transfer the key.
:keyword str encryption_scope:
A predefined encryption scope used to encrypt the data on the service. An encryption
scope can be created using the Management API and referenced here by name. If a default
encryption scope has been defined at the container, this value will override it if the
container-level scope is configured to allow overrides. Otherwise an error will be raised.

An async callback to track the progress of a long running upload. The signature is

the wire if using http instead of https as https (the default) will
already validate. Note that this MD5 hash is not stored with the

"""Copies a blob from the given URL.
This operation returns a dictionary containing `copy_status` and `copy_id`,
which can be used to check the status of or abort the copy operation.
`copy_status` will be 'success' if the copy completed synchronously or
'pending' if the copy has been started asynchronously. For asynchronous copies,
the status can be checked by polling the :func:`get_blob_properties` method and
checking the copy status. Set `requires_sync` to True to force the copy to be synchronous.
The Blob service copies blobs on a best-effort basis.
The source blob for a copy operation may be a block blob, an append blob,
or a page blob. If the destination blob already exists, it must be of the
same blob type as the source blob. Any existing destination blob will be
overwritten. The destination blob cannot be modified while a copy operation
is in progress.
When copying from a page blob, the Blob service creates a destination page
blob of the source blob's length, initially containing all zeroes. Then
the source page ranges are enumerated, and non-empty ranges are copied.
For a block blob or an append blob, the Blob service creates a committed
blob of zero length before returning from this operation. When copying
from a block blob, all committed blocks and their block IDs are copied.
Uncommitted blocks are not copied. At the end of the copy operation, the
destination blob will have the same committed block count as the source.
When copying from an append blob, all committed blocks are copied. At the
end of the copy operation, the destination blob will have the same committed
block count as the source.
:param str source_url:
A URL of up to 2 KB in length that specifies a file or blob.
The value should be URL-encoded as it would appear in a request URI.
If the source is in another account, the source must either be public
or must be authenticated via a shared access signature. If the source
is public, no authentication is required.
Examples:
https://myaccount.blob.core.windows.net/mycontainer/myblob
https://myaccount.blob.core.windows.net/mycontainer/myblob?snapshot=
https://otheraccount.blob.core.windows.net/mycontainer/myblob?sastoken
:param metadata:
Name-value pairs associated with the blob as metadata. If no name-value
pairs are specified, the operation will copy the metadata from the
source blob or file to the destination blob. If one or more name-value
pairs are specified, the destination blob is created with the specified
metadata, and metadata is not copied from the source blob or file.
:type metadata: dict(str, str)
:param bool incremental_copy:
Copies the snapshot of the source page blob to a destination page blob.
The snapshot is copied such that only the differential changes between
the previously copied snapshot are transferred to the destination.
The copied snapshots are complete copies of the original snapshot and
can be read or copied from as usual. Defaults to False.
:keyword tags:
Name-value pairs associated with the blob as tag. Tags are case-sensitive.
The tag set may contain at most 10 tags. Tag keys must be between 1 and 128 characters,
and tag values must be between 0 and 256 characters.
Valid tag key and value characters include: lowercase and uppercase letters, digits (0-9),
space (` `), plus (+), minus (-), period (.), solidus (/), colon (:), equals (=), underscore (_).
The (case-sensitive) literal "COPY" can instead be passed to copy tags from the source blob.
This option is only available when `incremental_copy=False` and `requires_sync=True`.
