Gentoo
It started with Brian Evans’ github repository, some good instructions on the mailing list for Building MariaDB on Gentoo, to a request for packaging, and guess what? Its now officially in Gentoo! Thanks Brian, and Robin Johnson!

Mark has now got a MariaDB category on his blog and the interesting things for you to grab are: …

Dear MariaDB users,

MariaDB 5.1.44, a new branch of the MySQL database which includes all major open source storage engines, myriad bug fixes, and many community patches, has been released.

This release is based on MySQL 5.1.44. In includes performance improvements with Maria temporary tables, removal of mutexes and the aim of removing compiler errors is being achieved quite well! For an overview of what’s new in MariaDB 5.1.44, please check out the release notes.

For information on installing MariaDB 5.1.44 on new servers or upgrading to MariaDB 5.1.44 from previous releases, please see the installation guide.

MariaDB is available in source and binary form for a variety of platforms and is available from the …

ScaleDB is proud to announce the introduction of a database that takes data storage to a new level, and a new altitude. ScaleDB’s patent pending “molecular-flipping technology” enables low energy molecular flipping that changes selected water molecules from H20 to HOH, representing positive and negative states that mimic the storage mechanism used on hard drive disks.

“Because we act at the molecular level, we achieve massive storage density with minimal energy consumption, which is critical in today’s data centers, where energy consumption is the primary cost,” said Mike Hogan, ScaleDB CEO. “A single thimble of water vapor provides the same storage capacity as a high-end SAN.”

The technology does have one small challenge: persistence. Clouds are not known for their persistence. ScaleDB relies on the Cumulus formation, since it is far beefier than some of those wimpy cirrus clouds. However, when deployed …

There have been a number of April fools jokes today so I thought I’d add my own to the list. While this sounds unexpected it’s actually no joke.

I just accepted a position with Oracle yesterday but I can’t say any more about the details until the MySQL users conference in a few weeks.

A special thanks to Lenz, Kaj & Giuseppe that championed everything to make it all happen, I really didn’t have to do anything other then accept.

2010 will be an incredibly exciting year for database technology. The amount of stored information has long been increasing exponentially, presenting unprecedented challenges for modern technology companies. Dropping RAM prices and affordable multicore CPUs have drastically changed the hardware profile of a typical server machine from what it was only five years ago. The emergence of solid-state drives is about to revolutionize database systems, enabling new kinds of applications we can barely envision today.

The database technology we have been using for over four decades is about to become obsolete. At RethinkDB, we’re redesigning databases from the ground up to meet modern data management demands, and to take advantage of the latest advances in hardware. We’re working to breathe new life into database technology, from the low level intricacies of database internals, to high level data access technology.

To help us build a …

In a couple of weeks at the MySQL Conference, I will be co-presenting a session “Database Operations At Scale” with some of my colleagues from Facebook’s database operations team.

What sorts of questions do you folks have regarding database operations at Facebook? Leave a comment here and we’ll see if we can incorporate that into the presentation.

The InnoDB plugin will be the subject of the next North Texas MySQL Users Group on Monday April 5th. The InnoDB plugin has some big performance and scaling benefits. But there are some messy things you have to take care of before it will work.


All are welcome!

When I originally wrote the post on the MySQL Audit Plugin API, the API still wasn't documented, instead I got my information from the source and the samples. Just now, the documentation is available here, with some more specific information here.

I have a bug to report on the Plugin API though, which is that a user with root privileges can possibly uninstall the plugin, which will void any auditing. I'm not 100% how this works yet, but I am certain that for any serious use of auditing, you would possibly want the ability to not being able to unload a plugin. I'll get back to you on this.

April 1, 2010. Tokutek’s acquisitions of Oracle, Apple, HP, Microsoft and Google were today blocked by the European Union on the basis that the announced acquisitions were “in bad taste”. John Partridge, CEO of Tokutek said “They made us take our TokuFish back. They made us take our TokuPad back. They made us take our stock back. And our stack. Now we’re just a handful of engineers building a MySQL storage engine.”

“But it’s a really good storage engine.”

This is the 184th edition of Log Buffer, the weekly review of database blogs. I’ve edited a couple of Log Buffers before, but this is the first time I get to post directly to the Pythian blog. Just one of the many perks of being a Pythian employee ;)

On the Oracle front:

It is always good to start the day with a pop quiz to get the brain into gear: Charles Hooper posted a 3-part series with seemingly innocent True/False questions. He covers sorting, SQL tuning and …
