Exploration of Maximum Replay Speed in Group Replication

[wangbin579]

The figure illustrates the throughput of the MySQL primary at concurrency levels of 100, 150, 200, 300, and 400. In the figure, light gray indicates that the MySQL primary and secondaries are synchronized in speed, while dark gray signifies a slight lag of the MySQL secondaries behind the MySQL primary. Except for the case at 200 concurrency, where a 2-second delay was observed, the MySQL secondaries generally keep pace with the primary.
