When I published the MariaDB-5.3.4 sysbench results I said “if your workload includes complex (sub)queries, then you will probably benefit more from MariaDBs new optimizer features”. Today I will present some benchmark results for complex workload.
The benchmark is DBT3, an implementation of the TPC-H specification. DBT3 is written in C and hosted at Sourceforge.
The DBT3 benchmark can run at different scale factors – defining the size of the database. I used a scale factor of 30 which yields ~30GB of raw data and ~48GB of disk footprint. The machine running the benchmark had 16G of memory. …

We are pleased to announce the immediate availability of MariaDB 5.5.21-beta. MariaDB 5.5.21 is the first Beta release in the 5.5 series and follows the initial MariaDB 5.5.20-alpha release. We hope to follow it up soon with Release Candiate and then Stable (GA) 5.5 releases.
MariaDB 5.5.21 beta is a merge of MariaDB 5.3 and MySQL 5.5 with some limited additional bug fixes. In this release we have added some extra notable features including an improved thread pool, an updated SphinxSE storage engine for fulltext search, and the ability to selectively skip replication of binlog events. Extra features planned for MariaDB 5.5 will be pushed into subsequent releases. …

About MariaDB 5.3
The MariaDB 5.3 series introduces many new features, includes MariaDB
5.2, and is based on MariaDB 5.1 & …
We are pleased to announce the immediate availability of MariaDB 5.5.20-alpha. MariaDB 5.5.20 is the first Alpha release in the 5.5 series. We hope to follow it up soon with a beta 5.5 release.
MariaDB 5.5.20-alpha is a merge of MariaDB 5.3 and MySQL 5.5 with some limited additional bug fixes. This is the first 5.5-based release, and we are releasing it now, intentionally without any extra features (and with it missing some planned features) to get it into the hands of any who might want to test it. Extra features planned for MariaDB 5.5 will be pushed into future releases. …
Instead of the usual text-heavy blog posts that appear here, I thought it would be fun to mix things up and do a screencast showing exactly how easy it is to upgrade MySQL to MariaDB:

Some notes:
- The laptop I’m using had MySQL 5.1.55 installed with one database (apart from the system database). Installing MariaDB does not impact existing data in any way and once the install completed I had instant access to my data.
- As part of the install you are given the option to set a new password for the root user.

The MySQL community has something new on their radar. First up, it looks like MySQL is now part of Oracle Software Security Assurance, and this is something all MySQL users should be happy about. Next, it is worth noting that MySQL is now part of the Oracle Critical Patch Update (Oracle CPU), as the MySQL product line has made it into its first Oracle CPU advisory for January 2012.
As part of the MySQL community, CPU’s are new to us — they are released on the Tuesday closest to the 17th day of January, April, July and October.
