Well actually….no. The second Development Milestone Release of MySQL Cluster 7.2 introduces support for what we call “Multi-Site Clustering”. In this post, I’ll provide an overview of this new capability, and considerations you need to make when considering it as a deployment option to scale geographically dispersed database services.<?xml:namespace prefix = o />

You can read more about MySQL Cluster 7.2.1 in the article posted on the MySQL Developer Zone. 

MySQL Cluster has long offered Geographic Replication, distributing clusters to remote data centers to reduce the affects of geographic latency by pushing data closer to the user, as well as providing a capability for disaster recovery.

For those with an interest in MySQL, this week at Oracle OpenWorld has gotten off to a great start.  Demonstrating how Oracle drives MySQL innovation Tomas' "State of the Dolphin" keynote on Monday gave a great overview of the new MySQL products that have recently been delivered:

• MySQL Installer for Windows
• New MySQL Security and Scalability features 
• New MySQL High Availability features 
• New early access features in the MySQL 5.6.3 Development Milestone Release ("DMR") 
• New early access features in the …

In his Oracle OpenWorld keynote, Tomas Ulin, Oracle’s MySQL VP of Engineering, just announced exciting MySQL news, further demonstrating how Oracle drives MySQL Innovation! Here is a summary, with more detailed information following shortly:

1. Immediate Availability of the MySQL 5.6 2nd Development Milestone Release (DMR).

MySQL 5.6 builds on MySQL 5.5 by improving:

• The Optimizer for better performance and scalability
• Performance Schema for better instrumentation
• InnoDB for better transactional throughput
• Replication for improved data integrity with higher performance, availability and ease-of-use
• “NotOnlySQL” options for more flexibility in handling both key/value and complex query operations
• And more…

The MySQL 5.6 DMR #2 is available …

Background Knowledge

The progress of a task in TaskFreak! is shown as a percentage value and is not exactly visually appealing to quickly spot the progress. With a few minor alterations we can show the percentage completed bar that fills as the task progresses and a gradient bar indicating the progress along with the percentage value.

Hi all!
Here is a new blog; I'll post here some thoughts, tutorials... all related to my job - software developer at Oracle Corporation, working on MySQL. It will soon be nine years since I joined MySQL AB. After working on interesting topics: Replication, Online Backup, the Maria storage engine, each of them having taught me something, I'm now full-time on the Optimizer, and guess what - it is an interesting topic and it teaches me something!

Starting with MySQL 5.5.16 it is possible to setup password-less connections from clients into the MySQL server using the Windows SSPI authentication framework.

This functionality is provided by the Windows Native Authentication (WNA) plugin distributed with the commercial version of 5.5.16 server. The client-side support for WNA authentication is built into the client library (libmysql) distributed with the community version of 5.5.16 server and requires no additional configuration. Clients which link to 5.5.16 or higher version of libmysql will be able to connect to MySQL accounts using WNA authentication out-of-the-box.

For password-less connections to work, the server's administrator must install the WNA plugin in the server and create user accounts which use this plugin for authentication. It is also possible to allow connections to existing …

tl;dr : New 'automatic' optimistic conflict detection functions available giving the best of both optimistic and pessimistic replication on the same data
MySQL replication supports a number of topologies, and one of the most interesting is an active-active, or master-master topology, where two or more Servers accept read and write traffic, with asynchronous replication between them.

This topology has a number of attractions, including :

• Potentially higher availability
• Potentially low impact on read/write latency
• Service availability insensitive to replication failures
• Conceptually simple

It was a good to put  face to the names today at day 1 of #oow11 .

Tried to spend most of the day supporting the MySQL Community Kiosk with Sherri, Sarah and Dave. I was able to step into a couple sessions to show support as well.

Day two the MySQL sessions will be at the Marriot Marquis Hotel. Moscone South will have MySQL demos at the Exhibition Hall and Moscone West will have the MySQL Community Kiosk. Come on down and support MySQL!

MySQL Cluster is one of the fastest growing technologies available from MySQL today. To build on this momentum, we are announcing the second Development Milestone Release (DMR) at Oracle Open World 2011. The MySQL Cluster 7.2.1 builds upon the first DMR (7.2.0) announced in April 2011 with a range of new capabilities designed to enable next generation web services, enhance cross data center scalability and simplify provisioning.

Both Henrik and myself will be at Percona Live London 2011 in late October speaking on the wonderful Drizzle database server.

Other speakers at the conference will be talking about a wide range of topics surrounding the MySQL ecosystem including performance monitoring, backup, search, scaling and data recovery.

P.S. I do have a discount code – ask me in the comments for it!
