Question
I have a master-master
replication setup using MariaDB 10.5.8
regarding replication I have these common settings in both servers:
log_slave_updates = 1
gtid_strict_mode = 1
gtid_ignore_duplicates = 1
sync_binlog = 1
sync_relay_log = 1
sync_relay_log_info = 1
sync_master_info = 1
But some times depending on a query created by MySQL Workbench when dropping all tables I get this error the one breaks the replica:
Error on master: message (format)='Cannot delete or update a parent row: a foreign key constraint fails (%.192s)' error code=1451 ;
Any idea how I could prevent breaking the replica or fixing the problem without the need to do a full restore of an existing backup?
