Another configuration we can use to increase the efficiency of parallel execution on the slaves is to tune binlog_group_commit_sync_delay on the master. It also allows you to dynamically tune the above parameters to ensure the slaves are working hand in hand with the master, therefore, minimizing your time involved in a failover process.
