Queens Series Release Notes


Bug Fixes

  • MariaDB allows a server to be a master and a slave simultaneously, 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 slaves will fail to change to the new master. This will be fixed by first attaching the other replicas to the new master, and then dealing with the old master. Fixes #1754539


New Features

  • OpenStack Trove now supports enable or disable authentication for Redis datastore via the root-enable and root-disable API’s.

Bug Fixes

  • Fixes an issue in galera_common shrink that the wrong load removed nodes which could be missing a ClusterShrinkMustNotLeaveClusterEmpty exception or meet a NotFound error. Bug 1699953
