Transaction change data forwarding

Abstract:

Transaction change data replication includes identifying changes being made to a source database as part of an ongoing transaction at a source. The identifying is performed as the changes are made to the source database and as the transaction remains ongoing prior to commit or rollback thereof at the source. The source and a target are in a replication relationship in which data of the source database at the source is replicated to destinations in a target database at the target. The indications of the changes being made to the source are forwarded, to the target, as the transaction remains ongoing prior to commit or rollback thereof, and based on ending the transaction at the source, an indication of the transaction end is sent to the target.
