Percona XtraDB Cluster 5.6.28-25.14 is now available


Percona XtraDB Cluster 5.6.26-25.12Percona is glad to announce the new release of Percona XtraDB Cluster 5.6 on January 29, 2016. Binaries are available from the downloads area or from our software repositories.

Percona XtraDB Cluster 5.6.28-25.14 is now the current release, based on the following:

All of Percona software is open-source and free, and all the details of the release can be found in the 5.6.28-25.14 milestone at Launchpad.

For more information about relevant Codership releases, see this announcement.

Bugs Fixed:

  • 1494399: Fixed issue caused by replication of events on certain system tables (for example, mysql.slave_master_info, mysql.slave_relay_log_info). Replication in the Galera eco-system is now avoided when bin-logging is disabled for said tables.
    NOTE: As part of this fix, when bin-logging is enabled, replication in the Galera eco-system will happen only if BINLOG_FORMAT is set to either ROW or STATEMENT. The recommended format is ROW, while STATEMENT is required only for the pt-table-checksum tool to operate correctly. If BINLOG_FORMAT is set to MIXED, replication of events in the Galera eco-system tables will not happen even with bin-logging enabled for those tables.
  • 1522385: Fixed GTID holes caused by skipped replication. A slave might ignore an event replicated from master, if the same event has already been executed on the slave. Such events are now propagated in the form of special GTID events to maintain consistency.
  • 1532857: The installer now creates a /var/lib/galera/ directory (assigned to user nobody), which can be used by garbd in the event it is started from a directory that garbd cannot write to.

Known Issues:

  • 1531842: Two instances of garbd cannot be started from the same working directory. This happens because each instance creates a state file (gvwstate.dat) in the current working directory by default. Although garbd is configured to use the base_dir variable, it was not registered due to a bug. Until garbd is fixed, you should start each instance from a separate working directory.
