The new features in 5.2 are quite isolated and as most have been in use by members in the MySQL community for a long time. Current versions of MariaDB 5.2 are stable and can be downloaded from http://downloads.askmonty.org.
New storage engines
- Allows you to handle hierarchies (tree structures) and complex graphs (nodes having many connections in several directions)
- SphinxSE: Text search within MariaDB.
- A built-in Sphinx client which allows MariaDB to talk to searchd, run search queries, and obtain search results.
- Virtual columns
- Columns that are an expression and are calculated on retrieval.
- Extended User Statistics
- Client, User, Index and Table statistics.
- Segmented MyISAM key cache
- The key cache's global mutex is split into several mutex which gives a notable speed improvement under multi user load. We have registered up to 250% more performance thanks to this.
- Pluggable Authentication
- Authentication is done via an extensible plugin, which makes it easy to add any kind of authentication to MariaDB.
- Storage-engine-specific CREATE TABLE
- Allows one to specify additional attributes per field, index or table to the storage engine.
- Enhancements to INFORMATION SCHEMA.PLUGINS table
- We expose more information about the plugins, like maturity levels.
- Group commit for the Aria engine.
- Speeds up multi user inserts.
We have also done several smaller speed improvements, bug fixes and code cleanups.
