      For more information on how to use this operator, take a look at the guide:
      :ref:`howto/operator:GCSToSFTPOperator`
  
  :param source_bucket: The source Google Cloud Storage bucket where the
       object is. (templated)
  :param source_object: The source name of the object to copy in the Google cloud
      storage bucket. (templated)
      You can use only one wildcard for objects (filenames) within your
      bucket. The wildcard can appear inside the object name or at the
      end of the object name. Appending a wildcard to the bucket name is
      unsupported.
  :param destination_path: The sftp remote path. This is the specified directory path for
      uploading to the SFTP server.
  :param keep_directory_structure: (Optional) When set to False the path of the file
       on the bucket is recreated within path passed in destination_path.
  :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 gcp_conn_id: (Optional) The connection ID used to connect to Google Cloud.
  :param sftp_conn_id: The sftp connection id. The name or identifier for
      establishing a connection to the SFTP server.
  :param impersonation_chain: Optional service account to impersonate using short-term
      credentials, or chained list of accounts required to get the access_token
      of the last account in the list, which will be impersonated in the request.
      If set as a string, the account must grant the originating account
      the Service Account Token Creator IAM role.
      If set as a sequence, the identities from the list must grant
      Service Account Token Creator IAM role to the directly preceding identity, with first
      account from the list granting this role to the originating account (templated).
