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.
What is it?
- A straight merge of MariaDB 5.5.25 with Galera Cluster by Codership
- An alpha release which should not be used in production environments
- Using the Galera replication methodology, users get:
- Synchronous, multi-master replication with guaranteed data consistency
- This solution provides both read &

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 to add support to their apps is available in the AskMonty Knowledgebase:

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 tests. Tests for new features and regression tests — those that guarantee that a bug, once fixed, will never ever show up again. …

In end of May I told about the numbering plans for the next version of MariaDB in the blog post What comes in between MariaDB now and MySQL 5.6?. We received quite a lot of feedback and criticism on the idea of calling the next version MariaDB 10.0. Here is a little more information about why it makes sense to call the next version 10.0.
This is not news for most of you. MariaDB is not just a set of patches applied on top of MySQL. MariaDB includes features which are similar to the corresponding features in MySQL, but the implementations differ, like for example the thread pool, microsecond support and query annotations in RBR binlog. …
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 partitioned tables. We wanted a better solution because the query cache can be very useful and beneficial for partitioned tables, just like it is useful and beneficial for non-partitioned tables. …
Things are definitely a little quieter here in MariaDB land as many people embark on summer vacations to rest and recharge. However we will be at OSCON 2012. We have a booth in the non-profit/projects pavilion, amazing amounts of schwag, and the famous black vodka that Monty always brings with him. We plan to have a BoF on Thursday evening (come to D135 at 8pm), and we will be at the MySQL BoF on Wednesday evening as well, just for good measure.
Come say hi. Come tell us how you’re using MariaDB.

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 don’t use Launchpad Answers because we have the Knowledgebase.
With this move to hosted JIRA (yes, this is an important link: https://mariadb.org/jira) we can report bugs, have future plans, and also give users a roadmap which is pretty cool. …
