In the MySQL world, if replication is broken we all use the famous SET GLOBAL SQL_SLAVE_SKIP_COUNTER=1; to skip the replication error. It always works if it’s a traditional binlogs events-based replication and is helpful to quickly resume the replication. But does this same method work for GTID-based replication? Let’s see.
