      Original Downstream Change Summary

      New change stream event: endOfTransaction.
      In this ticket we only added support for it for unprepared (single-shard) transactions.
      Full work on this event can be tracked via PM-2782

      Description of Linked Ticket

      When we see committed unprepared transaction in DocumentSourceChangeStreamUnwindTransaction, we can safely append no-op oplog entry about the end of this transaction to the stream.

      This no-op entry should be filtered according to the namespaces, affected by the transaction.

      This entry should be transformed into change stream event. 

      Event should only appear if showExpandedEvents is true
