It has arrived, a little over a month from the last beta release, is MariaDB 5.3.1. It is a bug-fix update and as always the changelog lists everything that has been fixed. The release notes list all the changes present in the 5.3-series.

Many fixes are in the optimizer updates that showed itself in MariaDB 5.3.0-beta, plus backports from the MySQL 5.6 feature preview trees. Microsoft Windows is also important to the MariaDB project so there are plenty of updates for that platform. What are you waiting for, download it now.

Posted recently on the maria-developers mailing list, by Igor Babaev, Principal MariaDB developer at Monty Program is some interesting preliminary results for MariaDB 5.3.0 benchmarked against the DBT-3 benchmarking program.

DBT-3 is a benchmark to test a decision support workload, with a suite of business-oriented queries and concurrent data modifications.

Read Igor’s discoveries, which he ran on a laptop with 4 cores (multi-threaded = 8 cores in total), 8GB RAM and SSD on SuSE, and as Igor says, enjoy his numbers. It is a repeatable benchmark with all settings included. We’d like to see discussion continued on the mailing list!

Monty blogged about MariaDB 5.3 being released as a beta with 5.3.0. We also have a press release. Download it now and test the beta!

The MariaDB Project today announced the availability of MariaDB 5.3.0 Beta. It includes a large number of features and additions while still remaining backwards compatible to MySQL®.

“There are many optimizer changes which makes this a very interesting release, because people will notice that their queries run faster,” said Rasmus Johansson, COO of Monty Program Ab, a commercial backer of MariaDB. “The optimizer developers say it’s the biggest change to the optimizer in ten years”, he added.

A few highlights of the changes include subquery optimizations which allow subqueries to finally be usable and materialize. There are many join and disk access optimizations, including Classic Hash Join, Batch Key Access, Multi-Range-Read and Index Condition Pushdown. For fans of NoSQL, the HandlerSocket interface ships with MariaDB and 5.3.0 debuts support for dynamic columns (each row can have a different set of columns).

“We’ve spent years on many features, and I’ve even fixed some of my pain points,” says Michael Widenius, CEO of Monty Program Ab and the original developer of MySQL. “Things like a better optimizer, progress reporting and dynamic columns have been on my bucket list for a long time and I’m thrilled that we finally have it,” he added.

The beta release of MariaDB 5.3.0 is available for download at http://downloads.askmonty.org/ immediately. This MariaDB release is supported by a release partner, SkySQL Ab.
