(ENP Newswire Via Acquire Media NewsEdge) ENP Newswire - 06 February 2013 Release date- 05022013 - Redwood Shores, Calif. - Oracle today announced the general availability of MySQL 5.6, the world's most popular open-source database.

With increased performance, scalability, reliability and manageability, MySQL 5.6 helps users meet the most demanding Web, Cloud and embedded application requirements.

MySQL 5.6 improves developer agility with subquery optimizations, online Data Definition Language (DDL) operations, NoSQL access to InnoDB, new instrumentation in Performance Schema and better condition handling.

For more details, join the MySQL Technology Update webcast on Feb 14 at 10:00 a.m. US, Pacific Time.

In addition, Oracle is hosting the first Virtual Developer Day for MySQL on March 12 at 9:00 a.m. US, Pacific Time. The event will include presentations and hands-on labs to educate MySQL users on essential skills and the latest features in MySQL 5.6. Register here.

Continued Innovations for the MySQL Community New features and enhancements in MySQL 5.6 are available to MySQL users in the MySQL Community Edition.

MySQL 5.6 provides enhanced linear scalability, helping users to leverage modern hardware capabilities.

With this version, users can experience simplified query development and faster execution, better transactional throughput and application availability, flexible NoSQL access, improved replication and enhanced instrumentation.

Highlights of MySQL 5.6 include: Better Query Execution Times and Diagnostics provided through an enhanced MySQL Optimizer diagnostics: Subquery Optimizations: simplify query development by optimizing subqueries prior to execution. New efficiencies in how result sets are selected, sorted and returned deliver substantial improvement in query execution times. The Addition of Index Condition Pushdown (ICP) and Batch Key Access (BKA): can improve selected query throughput by up to 280x(1). Enhanced Optimizer Diagnostics: with EXPLAIN for INSERT, UPDATE, and DELETE operations. EXPLAIN plan output in JSON format delivers more precise optimizer metrics and better readability, and Optimizer Traces enables to track the optimizer decision-making process.

Greater Performance Throughput and Application Availability with an improved InnoDB storage engine: Up to 230 Percent Improvement in Transactional and Read Only Throughput: InnoDB has been re-factored to minimize legacy threading, flushing, and purge mutex contentions and bottlenecks, enabling better concurrency on heavily loaded OLTP systems, and resulting in significantly improved throughput for both transactional and read only workloads(2). Enhanced Availability: online DDL operations enable DBAs to add indexes and perform table alterations while the application remains available for updates. Full-Text Search with InnoDB: allows developers to build FULLTEXT indexes on InnoDB tables to represent text-based content and speed up application searches for words and phrases. Simple, Key Value Lookup: flexible NoSQL access to InnoDB provides simple, key-value lookup of InnoDB data via the familiar Memcached API. Users get the 'best of both worlds,' combining key-value operations and complex SQL queries in the same database.

Improved Scale-Out and High Availability: with new features in MySQL replication including: Self-Healing Replication Clusters: the addition of Global Transaction Identifiers and Utilities make it simple to automatically detect and recover from failures. Crash-Safe Replication enables the binary log and slaves to automatically recover correct positions in the replication stream in case of a crash, and resume replication without administrator intervention. Checksums maintain data integrity across the cluster by automatically detecting and alerting on errors. High Performance Replication Clusters: up to 5 times faster replication through Multi-Threaded Slaves(3), Binlog Group Commit and Optimized Row-Based Replication enable users to maximize the performance and efficiency of replication as they scale-out their workloads across commodity systems. Time-delayed Replication: provides protection against operational errors made on the master, for example accidentally dropping tables.

Enhanced PERFORMANCE_SCHEMA: new instrumentation enables users to better monitor most resource intensive queries, objects, users and applications. New summaries with aggregated statistics grouped by query, thread, user, host and object are also available. The enhancements allow for easier default configuration with less than five percent overhead.

MySQL 5.6 includes a number of additional enhancements including Geographic Information Systems - Precise Spatial operations, improved IPv6 compliance and optimized server defaults.

Supporting Quotes 'MySQL 5.6 Release Candidate received great feedback from the community and helped us to efficiently mature the technology to announce General Availability,' said Tomas Ulin, vice president of MySQL Engineering. 'The new features and enhancements that MySQL 5.6 delivers further demonstrate Oracle's investment in driving MySQL innovation, making MySQL a fantastic fit for today's most demanding Web, Cloud and embedded application requirements.' 'With this latest release, Oracle shows its ongoing commitment to the MySQL community,' said Carl Olofson, research vice president for Database Management and Data Integration Software at IDC. 'These are significant advances in MySQL technology, enabling this open source RDBMS to meet the needs and exceed the expectations of its large and growing body of users.' 'We have experienced tremendous demand for our MySQL cloud services over the past year,' said Brent Juelich, senior director, Managed Services, Savvis. 'Considering the dramatic performance improvements and the new features available in MySQL 5.6, along with the added value of MySQL Enterprise Edition, we fully anticipate even more interest in these offerings in the future.'
