Abstract: A trigger event is detected (402) and in response to the trigger event an apply engine stops applying data changes to at least one part of the target database (403). In response to stopping the applying of data changes a start load signal (SLS) is inserted into a log of the source database for identifying unreplicated data changes. Loading of a part of the data content from the master database to the target database is then initialised (406). After the loading has completed an end of load signal (ELS) is inserted into the log and the apply engine applies stored write statements while identifying and skipping all write statements whose data changes were already transferred to the target database by the loading.
