Oracle Introduces New DMR for MySQL 5.7 

Oracle announced the availability of a new Development Milestone Release (DMR) for MySQL 5.7. Available for download in the MySQL Developer Zone, this MySQL 5.7.4 DMR delivers improvements in replication, security, and instrumentation resulting in significantly higher performance and improved manageability over MySQL 5.6.

The Release Candidate of MySQL Fabric, providing high availability management and scale out through sharding is also available. MySQL Fabric is included in the Release Candidate version of MySQL Utilities 1.4.2. MySQL Workbench 6.1 is generally available today, delivering additional capabilities for performance assessment and query optimization.

In addition, Oracle is providing early access to features under development including Geographic Information System (GIS) and multi-source improvements, and a preview of MySQL Cluster 7.4, for community testing and feedback through http://labs.mysql.com.

New MySQL Enhancements Improve Performance, Scalability and Manageability

Performance and Scalability

-- MySQL DMR 5.7.4 provides performance and throughput improvements for Solid State Disks (SSD).
-- Improved InnoDB buffer pool and metadata locking deliver higher throughput, performance and scalability.
-- MySQL semi-synchronous replication performance enhancements.
-- Benchmark tests using SysBench Read-only Point-Selects, at 1024 connections, resulted in MySQL 5.7 delivering 512,000 QPS, 2x better than MySQL 5.6, and 3x better than MySQL 5.5.

Manageability

-- Optimizer enhancements provide more accurate cost calculations.
-- Performance Schema improvements, including added instrumentation.
-- Security enhancements, including Advanced Encryption Standard (AES) 256-bit encryption and new options for password management.

Part of MySQL Utilities, MySQL Fabric delivers high availability with automatic failure detection and failover as well as scale out through data sharding.

MySQL Workbench 6.1 delivers additional capabilities for performance assessment and query optimization including:

-- New performance dashboard and reports.
-- Enhanced Explain plans to help optimize query performance.
-- New MySQL “SYS” Schema, providing simplified views on MySQL performance schema, instrumentation schema and more.
