Galera Cluster for MySQL 5.7.39 released

Codership is pleased to announce a new Generally Available (GA) release of the multi-master Galera Cluster for MySQL 5.7, consisting of MySQL-wsrep 5.7.38 (release notes, download). This release incorporates all changes to MySQL 5.7.39, adding a synchronous option for your MySQL High Availability solutions.

We have backported the InnoDB wsrep applier lock wait timeout from 8.0 which introduces the variable innodb-wsrep-applier-lock-wait-timeout to improve the reliability in resolving cluster wide conflicts. We have also deprecated the variable wsrep_slave_UK_checks as the default behaviour has been changed to ON.

This is another rare release where you are also meant to continue using the Galera replication library 3.37 implementing the wsrep API version 25, from two releases past, as there was no changes made to the Galera replication library for this release.

For those eagerly awaiting our next MySQL 8.0 release, it is coming soon, so keep watching this space.

Please download the latest software and update your Galera Clusters! We continue to provide repositories for popular Linux distributions, and we encourage you to use them. Contact us more more information about what Galera Cluster Enterprise Edition can do for you.
