Transactional and parallel log replay for asynchronous table replication

A system, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive a replication log entry and an associated transaction commit log entry, the replication log entry and the associated transaction commit log entry together representing a database transaction to be replayed to a row at a replica table, the row at the replica table having a row-ID value and the replication log entry having a row-ID value that identifies a data state of the row at the replica table;
• dispatch the replication log entry to a parallel log replayer and the associated transaction commit log entry to a transaction commit log replayer;
• compare the row-ID value of the replication log entry to the row-ID value of the row at the replica table;
• replay the replication log entry at the parallel log replayer based on the comparison;
• and
• commit the database transaction to the replica table by replaying the associated transaction commit log entry at the transaction log replayer.

A tangible computer-readable device having instructions stored thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:

• receiving a replication log entry and an associated transaction commit log entry, the replication log entry and the associated transaction commit log entry together representing a database transaction to be replayed to a row at a replica table, the row at the replica table having a row-ID value and the replication log entry having a row-ID value that identifies a data state of the row at the replica table;
• dispatching the replication log entry to a parallel log replayer and the associated transaction commit log entry to a transaction commit log replayer;
• comparing the row-ID value of the replication log entry to the row-ID value of the row at the replica table;
• replaying the replication log entry at the parallel log replayer based on the comparison;
• and
• committing the database transaction to the replica table by replaying the associated transaction commit log entry at the transaction log replayer.
