'''
Creates a new blob from an array of bytes, or updates the content
of an existing blob, with automatic chunking and progress
notifications. Empty chunks are skipped, while non-emtpy ones(even if only partly filled) are uploaded.
:param str container_name:
Name of existing container.
:param str blob_name:
Name of blob to create or update.
:param bytes blob:
Content of blob as an array of bytes.
:param int index:
Start index in the byte array.
:param int count:
Number of bytes to upload. Set to None or negative value to upload
all bytes starting from index.
:param ~azure.storage.blob.models.ContentSettings content_settings:
ContentSettings object used to set blob properties.
:param metadata:
Name-value pairs associated with the blob as metadata.
:type metadata: dict(str, str)
:param bool validate_content:
If true, calculates an MD5 hash for each page 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.
: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, or None if the total size is unknown.
:type progress_callback: func(current, total)
:param int max_connections:
Maximum number of parallel connections to use.
: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.
:param 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.
:return: ETag and last modified properties for the Page Blob
:rtype: :class:`~azure.storage.blob.models.ResourceProperties`
