Jan Lindström added a comment - 2023-03-28 05:00 I could see following use case for different domain_id's node1 <--->node2<--->node3 (Galera cluster domain_id=1) node4<--->node5<--->node6 (Galera cluster domain_id=2) | (Async replication) | (Async replication) node7<--->node8<--->node9 (Galera cluster domain_id=3) Here I have 2 master Galera clusters and one replica Galera cluster. Even when lets say master Galera cluster with domain_id=1 goes down and we change master, I do not see reason to ignore some events from certain domain. Note that inside a cluster domain_id must be the same as documented and currently I do not see reason to change that. If this feature is important to customer(s), please provide more detailed description on use case and how it should work. Current description is too vague for feature request. Therefore, I can't evaluate possible consequences and/or task estimates.

Richard Stracke added a comment - 2023-06-07 11:13 janlindstrom You only mention here wsrep_gtid_domain in your setup. The main purpose of this ticket is to ignore gtid_domain_id. gtid_domain_id will be used, if a transaction was written to the node, which was not replicated to other nodes for different reasons.
