Abstract
Methods and apparatus are provided for performing source-side merging of distributed transactions prior to replication, wherein a distributed transaction occurs at a plurality of nodes. A first node includes a database and an audit trail that stores database change events from the database of the first node. One or more other nodes each include a database and an audit trail that stores database change events from the database of the respective node. In use, a transaction is initiated which updates the database of the first node and the database at one or more of the other nodes. The database updates are captured in the audit trails of the respective nodes involved with the transaction. The first node receives and merges the database change events from the audit trails of each of the nodes involved in the transaction. The merged database change events are replicated via a replication engine only from the first node.
