        :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.

            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:

            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.

            A callback to track the progress of a long running download. The signature is
