Orchestrator & Pseudo-GTID for binlog reader failover
+0 Vote Up -0Vote Down

One of our internal apps at Booking.com audits changes to our tables on various clusters. We used to use tungsten replicator, but have since migrated onto our own solution.

We have a binlog reader (uses open-replicator) running on a slave. It expects Row Based Replication, hence our slave runs with log-slave-updates, binlog-format='ROW', to translate from the master's Statement Based Replication. The binlog reader reads what it needs to read, audits what it needs to audit, and we're happy.

Semi-synchronous Replication Performance in MySQL 5.7
Employee_Team +0 Vote Up -0Vote Down

With MySQL 5.7 becoming GA it’s a good time to highlight how much performance has improved in replication since the 5.6 era. A previous blog post focused on the performance of the multi-threaded slave applier and on this one the target is the semi-synchronous replication plug-in (SemiSYNC), whose performance has improved greatly.…

MySQL 5.7 first impressions on group-replication
+3 Vote Up -0Vote Down

During the last few weeks I’ve been testing and playing a bit with the new group-replication plugin available for MySQL 5.7. Before continuing I’d like to clarify some aspects: the plugin is only available in labs and is not yet ready for production. The current version is 0.6. I used 5.7.9 GA running in a Vagrant 3 nodes cluster with CentOS 7.
As an additional note, I’ve tested previous version of plugin 0.5 against 5.7.8.rc and there are some good changes, so I recommend starting with the GA version.

These days everybody is excited with recent announcement of MySQL 5.7.9 GA release. If you are not aware of this event yet (I've noted it from numerous posts even during my short vacation), wait for the Oracle Open World 2015 to begin tomorrow to announce it even wider and louder!

MariaDB 10.1 is stable GA
+0 Vote Up -0Vote Down

With the release of 10.1.8, MariaDB takes a next step. MariaDB 10.1 is now considered a stable release.

MariaDB 10.1 has a couple of main themes:

  • Security
  • High Availability
  • Scalability

During the last few years there have been many request for more security features in MariaDB. Actually it’s a trend in general. Since open source software is getting more attractive all the time, more functionality is wanted in areas where proprietary software typically has been leading. This is especially true for databases. In addition data privacy is a very hot topic.

The big new thing in security for MariaDB 10.1 …
