Change Description

MySQL's binary log (binlog) records all database data changes (such as INSERT, UPDATE, and DELETE), and is primarily used for data replication and restoration. It has a significant impact on performance in high-concurrency write scenarios.

The binlog optimization feature identifies hotspot functions that affect performance in write-only scenarios and optimizes these functions through binlog pre-allocation, lock splitting, and writeset_history data structure replacement. This reduces binlog write overhead and improves performance in write-only scenarios.
