Methods and apparatus, including computer program products, are provided for data replication. In one aspect, there is provided a computer-implemented method. The method may include providing an initial load of a data item from a source system to a target system, wherein the data item is associated with a trigger maintained at the source system; recording a change in a log, when a change to the data item at the source system causes the trigger to prompt the recording; extracting the change from the log to enable at least a confirmation of a consistency of the change; and providing the extracted change to a replication server configured to write the change to the target system. Related apparatus, systems, methods, and articles are also described.
