Our goal at Continuent is to be the go-to guys for database scale-out. Last Thursday we opened up a new community site for scale-out software at http://community.continuent.com. The site is driven by Joomla and has a number of very nice additions like Fireboard Forums and Mediawikis for each project. The first day or two was a bit bumpy as we nailed down some final issues, but most features are now working. We hope the result will be a nice place to meet other people who are interested in database scale-out and share ideas as well as software.

As you will see when visiting the community site, we have a variety of projects that we collectively call the Tungsten Scale-Out Stack. We have had this …

Though the event is still happening in Charlottesville, VA Nov. 14-16th (Fri night through Sunday), the new web page for OpenSQL Camp is http://www.opensqlcamp.org. The content has been ported over to MediaWiki, and a captcha has been put in place that is activated on any page change that adds an external URL.

Whether you are into MySQL, PostgreSQL, Drizzle, or some other open source SQL database, go forth and register for OpenSQL Camp, without having to login! (Disclosure: if you do not create a login, your IP is tracked.)

Welcome to the 112th edition of Log Buffer, the weekly review of database blogs.

First, thanks to last issue’s contributors–Joe Izenman, Dan Norris, and Jason Massie–for snatching victory from the jaws of defeat and making LB#111 a worthwhile read. That’s what it’s all about!

Oracle’s up first, starting with our old friend Doug Burns and his Time Matters series, in which he holds up to the light the concept of …

Continuent is probably best known for its database clustering technology for MySQL, as well as PostgreSQL, but the company has for some time had its sights set on expanding beyond open source databases and enabling horizontal database scalability.

It has just taken a major step towards delivering on both counts with the launch of Tungsten, its new stack of open source middleware technologies designed to enable low-cost databases to scale horizontally for database failover and continuity.

Tungsten includes includes Sequoia, the existing …

Today Continuent is publishing the Tungsten Replicator, which provides advanced open source master/slave replication for MySQL. Publishing code is the first step to creating a robust alternative to current MySQL replication and will be followed by similar support for Oracle, PostgreSQL, and many other databases.

We started with master/slave replication on MySQL for a very simple reason: we know it well. And we know that while MySQL replication has many wonderful features like simple set-up, it also has many deficiencies that have persisted for a long time. Monty …

As part of a project of Technocation, Inc I took a whole bunch of videos at OSCon 2008. The conference was about a month ago, and about 2 weeks ago I’d finished processing and uploading all the videos, but it was only today where I had the 5-6 hours I needed to finish posting all the video, and making this matrix of video.

The video may not be the quality that the O’Reilly folks took and put up on blip tv’s OSCon site, but all the videos here are freely downloadable or playable in your browser.

Crisis has struck! This week’s Log Buffer editor had to beg off at the eleventh hour when his time vanished. It happens. But, in every crisis, an opportunity (well . . .  maybe, maybe not). The opportunity — an open discussion of this week’s best database blog articles. Readers in control.

Log Buffer is always looking for editors, so if you’d like to step forward and publish one on your own blog, read the Log Buffer guidelines and send me an email.

I’m going to go through my bookmarks and add my own presently. I hope to hear from you!

I’d like to share some great news — The Pythian Group and Open Query have become partners!

Open Query is a leading provider of high-quality MySQL, PostgreSQL and related training in Australia and New Zealand. They offer consulting services too, and are also known for their MySQL Graph Storage Engine. Feel free to browse through Open Query web-site for more info.

Open Query was founded by Arjen Lentz, who was employee number 25 at MySQL AB. If you follow the MySQL community then I’m sure you already read Arjen’s blog.

Welcome to the 110th edition of Log Buffer, the weekly review of database blogs.

From the MySQL side, Jeremy Zawodny gets things going this week. He writes about his doubts over the long-term performance of InnoDB, specifically the cost of multiversion concurrency control, particularly in a master-slave arrangment or a DW. Jeremy comments, “[The] disk bloat, fragmentation, and ongoing degradation in performance may be an argument for having some slaves that keep the same data in MyISAM tables.” His readers, however, point out some diagnostics and tools to remedy this concern.

Not that MyISAM is without foibles. Case in point, on the …

It’s time again for another edition of the weekly review of database blogs, Log Buffer. Since it was a big week for SQL Server, let’s start there, shall we?

The big news — SQL Server 2008 is released, as reported by SqlServer-qa.net, in seven different versions. Aaron Bertrand introduces a new kid on the block: SQL Server 2008 Web Edition — “. . . designed for highly available Internet …
