Description
Conclusion:
Monitor tracks and maintains the values of Master_SSL_Verify_Server_Cert, Replicate_Ignore_Server_Ids, Replicate_Do_Domain_Ids, Replicate_Ignore_Domain_Ids and SQL_Delay. During a switchover, the demoting primary inherits the values for these replication options from the previous replica (that is getting promoted). During rejoin, the joining replica uses the same values as the current primary used before being promoted.
Original description:
The monitor should track more replication options for servers, so that they can be applied when a server gets demoted or promoted. Ideally, the monitor would also set them correctly for servers rejoining the cluster. The options that need tracking include MASTER_SSL, IGNORE_SERVER_IDS, and others that apply to CHANGE MASTER TO. Certificate and keyfile paths are perhaps best ignored, as the correct values may depend on the server and thus are not transferable.
Additionally, the monitor could track the values of replication filter settings described at https://mariadb.com/docs/server/ha-and-performance/standard-replication/replication-filters
Only some of the filter settings can be runtime altered.
