Making it easier to follow and participate in MariaDB development

In June, I told about the consolidation of the MariaDB project tools. The final piece of this consolidation, to report bugs in the MariaDB project tracking tool called JIRA has now been finalized.

Bug reporting stays open! JIRA is open to anyone. The bug reports are publicly available, even without logging in and as a bonus it will be easier to follow what is going on in the project since you don’t have to jump between several tools to get the complete picture.

All bugs that existed in Launchpad have been migrated to JIRA. To find a bug that was originally reported on Launchpad use the following approaches:

  • If you happen to have the original bug id you can search for the bug by typing lp:bugid into the search field in the upper right corner of JIRA.

Announcing the Cassandra Storage Engine

We’re pleased to announce the first preview version of the Cassandra Storage Engine!

The Cassandra Storage Engine (SE) allows access to Cassandra databases from MariaDB/MySQL, and to provide data integration between the SQL and NoSQL worlds.

Have you ever needed to

  • grab some of Cassandra’s data from your web frontend, or SQL query?
  • insert a few records into Cassandra from some part of your app?

With Cassandra SE, this is easily possible. Cassandra SE makes Cassandra’s column families appear as MariaDB/MySQL tables that you can insert to, update, and select from. …

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

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

Explanation on MariaDB 10.0

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. …
