Abstract

The present disclosure relates to a method for data replication in a data analysis system (100). A source database system (101) of the data analysis system (100) comprises a transaction log (106) storing log records generated by database transactions. The method comprises in response to determining (303) that a received log record is generated by a database transaction that rolls back a change of another database transaction whose log records are buffered in at least one record buffer, data indicative of a log record generated by the other database transaction buffering (305) in the compensation buffer tag data. The tag data may be used (311) for replicating to a target database system of the data analysis system buffered log records of the record buffer which are not marked as compensation records.
