Use when a Galera cluster reports certification failures, ER_LOCK_DEADLOCK fires at COMMIT in a multi-master setup, wsrep_local_cert_failures keeps climbing, a hot-row is contended across nodes, or the cluster appears to be in split-brain. Prevents the common mistake of treating Galera ER_LOCK_DEADLOCK as a bug, retrying without backoff, ignoring hot-row design, running a 2-node Galera without an
