Queens Series Release Notes¶
MariaDB allows an server to be a master and a slave simutaneously, so when migrating masters, if the old master is reactivated before attaching the other replicas to the new master, new unexpected GTIDs may be created on the old master and synced to some of the other replicas by chance, as the other replicas are still connecting to the old one by the time. After that these diverged slave will fail changing to the new master. This will be fixed by first attaching the other replicas to the new master, and then dealing with old master. Fixes #1754539
OpenStack Trove now supports enable or disable authentication for Redis datastore via the root-enable and root-disable API’s.
