Abstract: Disclosed herein are system, method, and computer program product embodiments for coordinated replication of heterogeneous database stores. An embodiment operates by determining a synchronization point based on a commit log of a primary data center. A current log position of each of a plurality of secondary slave servers associated with a secondary master server of a secondary data center is requested. It is determined that the current log position of at least one of the secondary slave servers does not correspond to the logged position of a corresponding primary slave server relative to the synchronization point. An update indicating that the current log position of each of the secondary slave servers corresponds to the logged position of each of the relative corresponding primary slave servers is received. A replay of each of the secondary slave servers up to the synchronization point is initiated.
