Optimize Check for Parallel Replication Worker Thread Idleness

    XMLWordPrintable

Details

    Description

      Checking if the replication parallel workers are idle (rpl_parallel::workers_idle()) currently iterates through each parallel entry data structure, and locking each to view its last committed sub_id. This can be improved by using the pattern adopted in MDEV-30619 and comparing (rli->last_inuse_relaylog->queued_count == rli->last_inuse_relaylog->dequeued_count).

      This is a potential candidate for back-porting as well.
