Abstract
Disclosed herein are system, method, and computer program product embodiments for synchronizing lost change between a source table and a replica table. An embodiment operates by detecting a restart at a source node or a replica node. Row-ID values of replication log entries are then compared to row-ID column values of rows at a replica table of the replica node. Replication errors at a source table or the replica table are then determined based on the row-ID comparison. The rows of the source table and the replica table are then updated based on the determination.
