Oracle: Early Access to MySQL 5.6 New Features


Oracle has announced early access to new features of MySQL 5.6, which has been made available for the community to test, deploy, and provide feedback.

The latest features of the open source relational database management system (RDBMS) are focused on better scalability, performance, and flexibility. New MySQL replication features are said to help with performance, scale-out, and data integration.

Enhancements include the InnoDB storage engine, a new tool to provide support for full text search, greater performance for write-intensive applications, and better scalability under high concurrency/user loads.

The new MySQL 5.6 features are still in active development; after development is complete, these features are intended to move into future releases labeled as "development milestone" and "general availability" products.

"Oracle continues to advance MySQL to address the evolving needs of application developers," said Tomas Ulin, Oracle's MySQL vice president of Engineering. "This MySQL 5.6 early access release provides a preview of many important features that deliver enhanced performance, flexibility, and scalability, and gives the MySQL community an opportunity to provide feedback to Oracle."

New with this release is InnoDB Full-Text Search, a function that allows users to build full text indices and search for text-based content stored in InnoDB tables — and supports fast and accurate search on document content.

Also new with this release:

  • InnoDB Buffer Pool Pre-loading Options: provide new manual and automated options that allow the InnoDB buffer pool to preload and significantly shorten the warm-up times after server restart.

  • Larger InnoDB Redo Log Files: increase the maximum size of InnoDB redo log files from 4 GB to 2 TB, helping improve the performance of applications with write-heavy workloads or long running transactions.

  • Binlog Group Commit: delivers improved performance of MySQL replication, with Group Commit applying updates to the binary log in parallel and then committing them as a group to the binlog on disk.

Finally, MySQL 5.6 also features the Binlog API. This will enable MySQL users to integrate MySQL with both new and legacy applications and data stores. According to Oracle, "It allows developers to reduce the complexity of integration by standardizing their SQL data management operations on MySQL, while replicating data to other applications within their data management infrastructure."
