The primary objective of this release was to radically improve performance for subqueries, as well as for joins and single-table queries over large data sets. The MariaDB 5.3 release is based on MariaDB 5.2 (and therefor, MariaDB 5.1 & MySQL 5.1).
Noteworthy improvements in this release include:
- The biggest redesign for the MariaDB optimizer in 10 yrs
- NoSQL support
- Replication and binary logging
- Support for new datatypes
- Enhanced Windows performance
