Abstract:
Techniques are provided for eager replication of uncommitted transactions. A first plurality of change records is received, corresponding to database changes applied to a source database in a first transaction. First transaction dependency data is computed based on the first transaction. At least a portion of the first plurality of change records is applied to the target database before processing a commit record indicating that has been committed on the source database. Target dependency data is updated after processing the first commit record to reflect completion of the first transaction, the target dependency data including dependency data for a plurality of transactions applied or scheduled to be applied on a target database.
