Parameters

  • sftp_source_path (str) – 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.

  • container_name (str) – Name of the container.

  • blob_prefix (str) – Prefix to name a blob.

  • sftp_conn_id (str) – The sftp connection id. The name or identifier for establishing a connection to the SFTP server.

  • wasb_conn_id (str) – Reference to the wasb connection.

  • load_options (dict | None) – Optional keyword arguments that WasbHook.load_file() takes.

  • move_object (bool) – 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.

  • wasb_overwrite_object (bool) – 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.

  • create_container (bool) – 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.
