Abstract:
1. A method for incremental replication of one or more changes made to at least one partition in a state based distributed database synchronization system, the distributed database synchronization system having at least one source server initiating an incremental replication session with one or more destination servers, the method comprising: determining, by the source server, a replication state of the destination server; if the destination server has one previously established yet unsatisfied synchronization point, forming a starting synchronization point by: if the destination server has provided no synchronization point to the source server, generating a starting synchronization point by the source server indicating the corresponding type identifier, target state, and current key; and starting the incremental replication of the partition according to the starting synchronization point, wherein the incremental replication session for the destination server is completed when the target state thereof is reached.
