Igor Mazur	54b8856b87	MDEV-14528 Track master timestamp in case rolling back to serial replication ... When replicated events are from Master unaware of MariaDB GTID their handling by the Parallel slave misses Seconds_Behind_Master updating. In the bug condition the Show-Slave-Status' field remains unchanged. Because in such case event execution is sequential the bug is fixed with deploying the same logics as in the explicit single-threaded mode with is to set Relay_log_event::last_master_timestamp member early at the end of event reading from the relay log.	2018-11-06 21:11:49 +02:00

unknown	ec374f1e53	MDEV-5769: Slave crashes on attempt to do parallel replication from an older master ... Older master has no GTID events, so such events are not available for deciding on scheduling of event groups and so on. With this patch, we run such events from old masters single-threaded, in the sql driver thread. This seems better than trying to make the parallel code handle the data from older masters; while possible, this would require a lot of testing (as well as possibly some extra overhead in the scheduling of events), which hardly seems worthwhile.	2014-03-04 08:48:32 +01:00
