7,613,740 - Control of a data replication engine using attributes associated with a transaction

A data replication engine is controlled in a system that replicates data associated with a plurality of transactions from a source database to a target database. The system includes a change queue that contains transaction data associated with the transactions. The system maintains one or more attributes outside of the change queue which are associated with transactions. One or more attributes outside of the change queue are identified which are associated with a transaction. The one or more of the identified attributes are then used to control the replication engine.
