bool
When true, write the subscription name, message_id,
publish_time, attributes, and ordering_key as additional
fields in the output. The subscription name, message_id, and
publish_time fields are put in their own fields while all
other message properties other than data (for example, an
ordering_key, if present) are added as entries in the
attributes map.
