With all of the new news coming out right now, it can be easy to miss or overlook some of the new features.

While there’s been a lot of talk about MySQL 5.6 Replication, I specifically wanted to mention the new ‘mysqlfailover’ and ‘mysqlrpladmin’ utilities.

These are two new MySQL replication utilities (results of the new Global Transaction Identifiers (GTIDs) in MySQL 5.6).

Let me quote the MySQL 5.6 Replication article for both of these utilities:

mysqlfailover

“Provides continuous monitoring of the replication topology, enabling failover to a slave in the event of an outage on the master.

The default behavior is to promote the most up-to-date slave, based on …

The new MySQL 5.6 Development Milestone Release (DMR) includes many new enhancements. One of the most impressive is the use of Global Transaction Identifiers (GTIDs) for replication. With GTIDs enabled, administrators no longer need to keep track of binary log files and positions. In a nutshell, GTIDs simplify the setup and maintenance of replication.

Clearly, switchover is an elective operation and failover is performed when there are issues with the master.

The GTID utilities are included in release-1.0.5 of MySQL Utilities. They are included as a plugin for MySQL Workbench or via …
