ABSTRACT:
A system and method is presented for incremental replication of changes in a state based distributed database synchronization system. If a destination server has one previously established yet unsatisfied synchronization point, a starting synchronization point is formed by extracting the unsatisfied synchronization point from the destination server, identifying a type identifier within the extracted unsatisfied synchronization point identifying a predetermined set of synchronization algorithms and an execution order thereof, identifying a current key within the extracted unsatisfied synchronization point which indicates one of the predetermined set of synchronization algorithms to be started for execution, and adjusting a target state of the destination server to one older than or equal to an established target state specified by the extracted unsatisfied synchronization point. If the destination server has provided no synchronization point, the starting synchronization point is generated by a source server indicating its desired type identifier, target state, and current key.
