Database Cluster Replication

Hi All,

I have two database cluster, let say cluster A with cluster B. Cluster B is replication from Cluster A through Cluster B Node 1 using master slave replication from Cluster A. Cluster A has wsrep_gtid_domain_id = 100, and Cluster B has wsrep_gtid_domain_id = 200. When i start the replication slave on Cluster B, why the gtid_binlog_pos value still '100-xxx-xxx' which is that is wsrep_gtid_domain_id of Cluster A? Thanks.

Regards,

The gtid_binlog_pos is mean to container the gtid of where the log was generated. Log changes ma\de in cluster will have a domain_id of 200.
