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.

Abstract: Disclosed herein are system, method, and computer program product embodiments for replicating a database transaction to a replica table. An embodiment operates by receiving a replication log entry and an associated transaction commit log entry for a database transaction to be replayed to a row at a replica table. A row-ID value of the replication log entry is compared to a row-ID column value of the row at the replica table. The replication log entry is then replayed at a parallel log replayer based on the comparison. The database transaction is then committed to the replica table by replaying the associated transaction commit log entry at a transaction log replayer.

Abstract: Disclosed herein are system, method, and computer program product embodiments for removing a deadlock during replication from distributed source tables to a replica node. An embodiment operates by detecting a deadlock at a parallel log replayer at a replica node. A first replication log entry from a queue at the parallel log replayer is then selected based on whether removing the first replication log entry from the queue removes the deadlock. The first replication log entry is then forwarded to a waiting queue. A second replication log entry is then replayed at the parallel log replayer. After replaying the second replication log entry, the first replication log entry is replayed at the parallel log replayer.
