Sun Microsystems Announces MySQL 5.1

Sun Microsystems today announced the pending general availability of MySQL 5.1, a new version of the popular open source database. A near-final release candidate of the GPL software is available for download now at http://dev.mysql.com/downloads/.

MySQL 5.1 features a number of new enterprise enhancements, including:

  • Table and Index Partitioning
    MySQL 5.1 supports five forms of horizontal data partitioning: range, hash, key, list, and composite (sub-partitioning). By partitioning table and index data, faster query response times can be achieved as only the relevant partitions of data need to be scanned, instead of the entire table or index. Further, various storage and other maintenance operations are made much easier and accomplished more quickly via partitioning.
  • Row-Based and Hybrid Replication
    Two new replication options are now available in MySQL 5.1. Row-based replication replicates the data changes (rather than the actual SQL statements) between a master server and its slave servers, and hybrid replication uses either statement-based or row-based replication depending on the individual SQL operations - these achieve and maintain the most efficient and safest replication scheme for the application.
  • Event Scheduler
    This new tool allows developers and DBAs to automatically schedule common recurring SQL-based tasks to execute on the database server. It provides greater support for database-specific tasks than is available through CRON in Linux or Unix(R) or the Microsoft Windows task scheduler.
  • New Upgrade Advisor in MySQL Enterprise Monitor
    Available to MySQL Enterprise subscribers, the new Upgrade Advisor provides automated rules that monitor and advise DBAs about specific bugs that can might impact their deployed versions of MySQL 5.1. When potential issues are detected, subscribers are given recommendations how to upgrade their database servers to correct the problem.

MySQL 5.1 is scheduled to be generally available this quarter for a wide variety of hardware and software platforms, including Red Hat Enterprise Linux, SuSE Enterprise Linux Server, Microsoft Windows, Solaris 10 Operating System, Macintosh OS X, Free BSD, HP-UX, IBM AIX, IBM i5/OS and other popular Linux distributions.

The MySQL 5.1 GA release will be available in three ways to serve different audiences:

  • The MySQL Community Server
    The freely-available, open source version of Sun's MySQL database. Licensed under the GPL, this full-function software is targeted to a technical, do-it-yourself audience, who does not require commercial support or premium add-on services.
  • The MySQL Enterprise Server
    Available as part of a MySQL Enterprise subscription, this is the most reliable, secure, and up-to-date version of the MySQL database, targeted to corporate IT users. Subscribers receive monthly rapid software updates and quarterly service packs with the latest fixes -- along with access to proactive monitoring tools and 24x7 production technical support.
  • The MySQL Embedded Server
    This commercially-licensed version of the MySQL software allows ISVs and OEMs to embed or bundle a high-speed, small-footprint database with their own products, without the free-distribution requirements of the GPL license.

AMD 790GX Motherboard Sample Photos

Chinese website PC Online published photos of a motherboard based on the AMD 790GX chipset. This is an engineering sample of the Unika motherboard that, as you can see, still has no coolers installed.

According to their local manufacturers, UNIKA Shuangmin was the first to make a ready product on this core logic.

Hynix HY5PS121621c DDR2

Those who need more than the integrated AMD Radeon HD3300 core, can use PCI Express 2.0 and CrossFireX support (2 slots at 8x).

The AMD 790GX based product is to go on sale in May.
