In the last weeks / months, I have been working on understanding / improving MySQL startup with many tables.  I already wrote a post about my work (Faster MySQL Startup with Many Tables).  In that post, I link to a bug report (Bug #115988 : Too Much Disk Read on Startup, penalizing deployments with many tables).  In that bug report, I write, without much details, that the

MySQL 8.0 and newer change and improve how we measure and monitor replication lag. Even though multi-threaded replication (MTR) has been on by default for the last three years (since v8.0.27 released October 2021), the industry has been steeped in single-threaded replication for nearly 30 years. As a result, replication lag with MTR is a complicated topic because it depends on version, configuration, and more. This three-part series provides a detailed understanding, starting from what was originally an unrelated feature: binary log group commit.
