I am happy to announce that MariaDB 5.2.3 is now released as a stable release.

During the gamma period we did not receive any serious reports for issues in 5.2, so we are relatively confident that the new code is of decent quality.

You can read about the features of MariaDB 5.2 in my previous blog entry or in the fast growing MariaDB knowledgebase..

What is most interesting about MariaDB 5.2 is that most of the features came from the MariaDB/MySQL community, not from Monty Program Ab!

Without the community it would not have been possible to do a stable release so soon after the last release. Virtual columns, Extended User Statistics, Segmented MyISAM key cache, Pluggable Authentication, OQGRAPH and the Sphinx client are all from code provided by people outside of Monty Program Ab. Storage-engine-specific CREATE TABLE, Enhancements to INFORMATION SCHEMA.PLUGINS table and “Group commit” for the Aria engine were provided by us at Monty Program Ab.

Thanks also to all those who have reported and provided bug fixes for 5.1 and 5.2!

MariaDB 5.2.3 has all changes from MariaDB 5.1.50 and MySQL 5.1.51. (We are just about to release MariaDB 5.1.51)

Please report any issues to the MariaDB bugs database so that we can fix them!

We will continue to fix critical bugs in MariaDB 5.1, even if the
attention of bug fixes will now move to 5.2.

Now we are busy working on getting MariaDB 5.3 ready for beta. We have also started a merge of MariaDB 5.3 + MySQL 5.5 -> MariaDB 5.5 and hope to release this tree soon!

Happy database usage!

Recently I tested our new segmented key cache feature for MyISAM in MariaDB 5.2.2-gamma for performance gains. You can check our new features in MariaDB 5.2 in our Ask Monty Knowledge Base

You will also find the details about the segmented key cache feature in our Knowledge Base at:

We wrote a test in LUA for SysBench v0.5 called select_random_points.lua, to figure out the performance gain of splitting the key cache’s global mutex into several mutex under multi user load.

You can find all the details about the benchmark in our Knowledge Base article here:

The results were quite surprising, because we found up to 250% performance gain depending on the amount of concurrent users. On a side note we also found out that our new Intel system with 24 virtual cores has more than a 10 times performance advantage compared to our older 4 core system.

And the winners are, …

There was quite a rush for the t-shirts and we have our three winners:
