MariaDB Galera Cluster Alpha immediately available
Today we’re pleased to announce the availability of MariaDB Galera Cluster!
With this release, we’re addressing the numerous requests we’ve received over the past few months for a MariaDB-based Galera Cluster. MariaDB, the more reliable, performant, feature-complete & backwards compatible MySQL database becomes even more attractive by making it available for Galera Cluster.

The Explain Analyzer and HeidiSQL
A few months ago we announced the EXPLAIN Analyzer, a simple tool to help you understand how MariaDB / MySQL was running queries. For users of HeidiSQL this is now even easier. As discussed in their news post you can now send a query to the EXPLAIN analyzer with a single click.
We hope this helps both new and experienced users better understand the queries they run.
More information about the EXPLAIN Analyzer and the simple API client authors can use […]

Disappearing test cases or did another part of MySQL just become closed source?
About a week ago I was looking at MySQL 5.5.27, and noticed a curious thing. Despite the fact that the new MySQL release contained its usual share of bug fixes, not a single one of them was accompanied with a test case.
Now, let me tell you something about tests. For many years MySQL was using its own testing framework, called mysql-test. The first version was written as early as 1999. Over the years it has accumulated a lot of […]

The Query Cache and Partitions
Like others we were not satisfied with the fix for a bug in MySQL which caused the query cache and partitioning to not work reliably together. The bug, in simple terms, was that if the query cache was enabled and you used partitioned tables and if a partitioned table was using a transactional engine like InnoDB or XtraDB, the query cache could, under certain circumstances, return incorrect results.
Returning incorrect results is a definite, high-priority bug. However, the upstream fix was to disable all caching of queries from […]

Consolidating MariaDB project tools
It is not a secret that we’ve been kicking the tires and playing with JIRA for project management. After using it since the beginning of the year most of us like the feel of it and we’ve decided that it makes sense to start using it more.
As you know, the MariaDB project has many fragmented resources. We report bugs in Launchpad. We store our plans in worklog. We’ve never used the Launchpad Blueprint feature for this very reason. We […]

Monty Program & SkySQL: a statement on the serious security vulnerability that was found in MariaDB and MySQL
Over the past few days extensive conversations around a new security vulnerability in MariaDB and MySQL have taken place.
It all started as a chain reaction when Monty Program publicly disclosed information about the flaw they had found and about how to make sure your MariaDB and MySQL installations can be fixed. The initial information got assigned the security vulnerabitlity identifier CVE-2012-2122 and the contents can be seen e.g. here http://seclists.org/oss-sec/2012/q2/493.
The bug was found two months ago on April […]

What comes in between MariaDB now and MySQL 5.6?
We’re quite happy that we’ve released four major releases that are production ready (better known as generally available or GA in the MySQL world) in the last 26 months. That is just a little over two years, and a whole lot of features. In that same time, MySQL has seen one GA release (MySQL 5.5) and we’re all eagerly awaiting the upcoming MySQL 5.6.
You’ll note that we built MariaDB 5.1, 5.2, and 5.3 based on the MySQL 5.1 codebase. […]
