I have a PXC cluster with :
| binlog_gtid_simple_recovery | OFF |
| enforce_gtid_consistency | OFF |
| gtid_deployment_step | OFF |
| gtid_executed | |
| gtid_mode | OFF |
| gtid_next | AUTOMATIC |
| gtid_owned | |
| gtid_purged | |
| simplified_binlog_gtid_recovery | OFF |
when I change the master of a PXC attached ASYNC slave, no issues. This is contradictory to my believe - I can not remember where I read this: need to enable GTID to smoothly switch master in the PXC . Please shed some light.
