Mirror resynchronization of bulk load and append-only tables during online transactions for better repair time to high availability in databases

摘要

In a mirrored database system, mirror resynchronization of bulk load and append-only tables during ongoing transactions is optimized for quick repair and high availability by catching up any changes to primary database tables that have not been made to mirror database tables during the transaction itself, and making changes due to ongoing transactions when the databases are synchronized to the resynchronization process.
