MySQL 5.6 + GTID & MariaDB 10 replication
While at the keynote of Tomas Ulin at Percona Live MySQL Conference & Expo Santa Clara 2014, he asked the audience what they were running, and most of the audience was on MySQL 5.5 while about 15% of the audience was on MySQL 5.6. This number is steadily increasing I’m sure, so one thing that becomes important is that people will probably start turning on Global Transaction Identifiers (GTIDs).
As you may already know, MariaDB 10 has a different implementation of Global Transaction ID. To me, this poses a problem in a mixed use environment (or even a migration scenario). Which is why MDEV-4487 is so important: it is a feature request to allow replication from MySQL 5.6+ when GTID is enabled on the master.
If you think the issue is important, you can vote and watch the issue on JIRA. I for one think this should be fixed for 10.0.11 or 10.0.12 and not wait for the 10.1 timeframe. Best not to comment here, focus on the JIRA request, MDEV-4487.
