Replication Change Log

All modifications received by a master replica are recorded in a change log. A change log is maintained on all master replicas and hub replicas.

If your application needs to read the change log, use the retro change log plug-in for backward compatibility. For more information about the retro change log plug-in, see Replication and the Retro Change Log Plug-In.
