Today marks a milestone in terms of the MariaDB project – going forward, the MariaDB project plans to use Github and git for source code management. The migration happens from Launchpad and the bzr tool.
The 10.1 server development (under heavy development now) will happen on Github. You can check it out here: https://github.com/MariaDB/server. Feel free to watch, star or even fork the code, and send us contributions!
Previous maria-captains should now provide their Github IDs so that they can be accorded similar status. Send the IDs to the maria-developers mailing list. …
Ben Forta, the author of MySQL Crash Course and Sams Teach Yourself SQL in 10 Minutes, has written what I believe is the first MariaDB-specific book: MariaDB Crash Course. I just received word from Ben that the book is now shipping.
Most MySQL books can, of course, be used to learn almost everything you need to know about using MariaDB. But with all of the features and abilities MariaDB has gained in the MariaDB 5.2 and MariaDB 5.3 releases, it’s nice there is now a book specific to MariaDB. …
Quick pointer that MariaDB 5.2.7 is now released. Highlights from the release notes: RHEL 5 RPMs (in addition to the CentOS 5 RPMs), and the inclusion of the HeidiSQL GUI client for the Windows MSI package. As always, the complete changelog, and what are you waiting for – download it now and give it a try!
Dear MariaDB users,
MariaDB 5.2, a branch of the MySQL database which includes all major open source storage engines, myriad bug fixes and many community patches, has been released. It has all changes up to MySQL 5.1.51.
For an overview of what’s new in MariaDB 5.2.3, please see the release notes (5.2.2, 5.2.1, and 5.2.0 also).
MariaDB 5.2 includes a number of user enhancements including:
- Improved user statistics which help understand server activity better and identify the source of the load
- VIRTUAL and PERSISTENT virtual columns
- Group commit in the Aria storage engine (the engine formerly known as the Maria engine)
- Pluggable authentication
- Segmented key cache for MyISAM to improve performance
- Two new storage engines: OQGRAPH and an interface to the full-text search engine Sphinx by way of SphinxSE.
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. …
