Description
GTID sequence drifts between Write node and appliers node by issueing some KILL QUERY statements on a Galera node which is operating user's transactions.
Data consistency is maintained and wsrep_last_committed is in sync.
NOTE: It's not always sufficient to issue one single KILL QUERY, I should do more fine grained research to determine what are the specific circumstances, in my current tests I reproduced it by killing some random mysqlslap queries.
GTID sequence de-alignment breaks among others maxscale auto-failover.
To make things more complicated in the current attached pictures test Writer is behind but in other tests Writer went ahead(see attached txt for 2nd test)
