MySQL Update

Oracle has announced a Development Milestone release for MySQL 5.7, with benchmarked speeds twice those of MySQL 5.6

MSQL  5.7.4, which is available for download as a Development Release, offers improvements in replication, security, and instrumentation.

A release candidate of MySQL Fabric, which can be used for high availability management and sharding support, is also available. MySQL Workbench 6.1 has also been released with the ability to assess performance and optimize queries.

Some of the improvements to the performance come from improvements in the handling of Solid State Disks (SSD). An improved InnoDB buffer pool and metadata locking are also included, giving higher throughput. The MySQL semi-synchronous replication performance has also been improved.

The various changes were benchmarked using SysBench Read-only Point-Selects, at 1024 connections, with MySQL 5.7 delivering 512,000 QPS, 2x better than MySQL 5.6, and 3x better than MySQL 5.5.

The management features have also been improved, with more accurate cost calculations from the optimizer. The Performance Schema has more instrumentation, and you can now use AES 256-bit encryption for password management.

Other improvements to MySQL 5.7 features include better GIS support including spatial index support in InnoDB, as well as improved accuracy and performance; and continued development of multi-source replication.

The changes to MySQL Workbench include new performance dashboard and reports; an enhanced version of Explain plans to help optimize query performance; and a new schema. The MySQL “SYS” schema gives you simplified views on MySQL performance and instrumentation schemas.
