MySQL-Sandbox is a great tool for testing a new release, and in fact this is what I do when a new MySQL tarball becomes available. I don't think many people are aware of the full testing capabilities of the sandbox, though.
When you think about testing, you may just think of creating a sandbox with the new tarball, and then hammering it with your pet procedure. That works, of course, as the main purpose of MySQL-Sandbox is to allow you to do just that. There is, however, a full test suite that can tell you in a short while if your tarball is compatible with the past or not.
This procedure is quite strict. It has happened several times that I caught a bug in a new release of MySQL, or Percona Server, or MariaDB, just by running this suite.
How MySQL-Sandbox gets testedBefore describing how to test, I would like to show what I do. When a new version of MySQL-Sandbox is ready …

It had been in the making for long time. Google announced that Google Code would be closing, and since then the Continuent team has been hard at work to handle the transition. You can guess it: this operation would have been quicker if it had been done by a small company like we were one year ago, but being part of a large corporation introduces some constraints that have affected our schedule.

However, our wish has always been, and still is, to keep Tungsten Replicator as an open source product, with full functionalities and with the full benefits that the open source development model offers.

Today, Tungsten Replicator is available on GitHub as …

In the previous article, we saw the basics of establishing replication from multiple origins to the same destination. By extending that concept, we can deploy more complex topologies, such as the point-to-point (P2P) all-masters topology, a robust and fast …

MySQL replication in action - Part 1: GTID & Co
In the latest releases of MySQL and MariaDB we have seen several replication improvements. One of the most exciting additions is the ability to enhance basic replication with multiple sources. Those who have used replication for a while should remember that one of the tenets of the “old” replication was that a slave couldn’t have more than one master. This was The Law and there was no escape ... until now. The only way to work around that prohibition was to use circular replication, also known as …
