   Bases: :py:obj:`airflow.models.BaseOperator`

   Transfer files to Azure Blob Storage from SFTP server.

       For more information on how to use this operator, take a look at the guide:
       :ref:`howto/operator:SFTPToWasbOperator`

   :param sftp_source_path: The sftp remote path. This is the specified file path
       for downloading the single file or multiple files from the SFTP server.
       You can use only one wildcard within your path. The wildcard can appear
       inside the path or at the end of the path.
   :param container_name: Name of the container.
   :param blob_prefix: Prefix to name a blob.
   :param sftp_conn_id: The sftp connection id. The name or identifier for
       establishing a connection to the SFTP server.
   :param wasb_conn_id: Reference to the wasb connection.
   :param load_options: Optional keyword arguments that
       ``WasbHook.load_file()`` takes.
   :param move_object: When move object is True, the object is moved instead
       of copied to the new location. This is the equivalent of a mv command
       as opposed to a cp command.
   :param wasb_overwrite_object: Whether the blob to be uploaded
       should overwrite the current data.
       When wasb_overwrite_object is True, it will overwrite the existing data.
       If set to False, the operation might fail with
       ResourceExistsError in case a blob object already exists.
   :param create_container: Attempt to create the target container prior to uploading the blob. This is
       useful if the target container may not exist yet. Defaults to False.
