MySQL 5.4: Greater Performance and Scalability
By Jennifer Glore on Apr 21, 2009
Today, at the MySQL Users Conference, Sun announced the release of MySQL 5.4. MySQL 5.4 is the result of many months of work by Sun / MySQL engineers. It delivers significant performance and scalability improvements to MySQL applications. A preview version of MySQL 5.4 is available now for download at http://www.mysql.com/5.4.
MySQL 5.4 Features & Benefits
A number of new enterprise features and compelling fixes are planned for MySQL 5.4, including:
- Scalability improvements -- these fixes allow the InnoDB storage engine to scale up to 16-way x86 servers and 64-way CMT servers, more than doubling its previous capability;
- Subquery optimizations -- improves the performance of analytic query operations, with some subqueries now executing in a fraction of the time compared to previous MySQL versions;
- New query algorithms -- utilizes main memory to speed up the execution time of multi-way joins, especially for MySQL Cluster because the number of round-trips between the server and cluster nodes is minimized;
- Improved stored procedures -- enables more robust error management through the implementation of the SIGNAL/RESIGNAL functions, so applications can more easily rely on stored procedures for business logic;
- Improved prepared statements -- Output parameters will now be supported in prepared statements, which increases their functionality;
- Improved Information Schema -- provides more metadata access to parameters and data return types that stored procedures use, which allows much more information to be made available for developers using connectors such as ODBC and JDBC;
- Improved DTrace support -- improves diagnostics and troubleshooting capabilities for MySQL on the Solaris(TM) Operating System.
Stay tuned for formal benchmarks on MySQL 5.4.
