We are pleased to announce the immediate availability of MariaDB 5.5.22-rc. MariaDB 5.5.22 is the first release candidate (RC) release in the 5.5 series and follows the MariaDB 5.5.20-alpha and 5.5.21-beta releases. We hope to follow it up soon with a Stable (GA) 5.5 release.
MariaDB 5.5 is a merge of MariaDB 5.3 and MySQL 5.5 with some limited additional bug fixes. Please see the What is MariaDB 5.5 page for an overview of MariaDB 5.5.
The Release Notes page has some notes on the release. There is also a Changelog available for those who are interested.

[Read more]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.
InnoDB has the problem of fluctuating table statistics, leading to rather unpredictable query plans. For this reason the benchmark tables were created with the …

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.
As with any beta release, MariaDB 5.5.21-beta should not be used on production systems.
The Release Notes page has some …

[Read more]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.
As with any alpha release, MariaDB 5.5.20-alpha should not be used on production systems.
The Release Notes page has some notes on the release. There is also a …
