Abstract

A method, a system, and a computer program product for performing testing of continuous log replays in a database system. A redo log generated for a data record in a database is received. The redo log is indicative of a change in persistency of the data record in the database. Based on the change in persistency recorded in the redo log, a redo handler in the plurality of handlers is selected for execution of a replay of the received redo log. Using the selected redo log, replay of the redo log is executed to generate a state of the data record prior to the change in persistency recoded in the redo log.
