I just thought I might link to an article on RegDeveloper called MySQL is the company's SQL now...

Go read it yourself, it is rather short, but interesting nevertheless. I especially like the sentence at the bottom: It remains to be seen whether the company fully understands, and can cope with, the culture shock it is about to suffer; as callers change from 'friends' to 'customers'.

This is what I have been thinking about too, when they started releasing enterprise builds more often than community builds (binary builds that is). In the past MySQL always suggested to use the binaries provided by them to rule out any effects that may be introduced by a 3rd party build process or patches. That made much sense to me.

However now they tell you that you can check the source …

I happened to run across a software company called LabKey recently.  A former colleague of mine from way back when, Adam Rauch, started doing work at the Fred Hutchinson Cancer Research Center a few years ago where he developed a system for analysing mass spectrometry data.  Adam was one of the original team at Microsoft that created Visual Basic and went on to create some other pretty amazing products there. 

LabKey developed the CPAS (Computational Portal and Analysis System) software as an open source science project offering web-based bioinformatics and collaboration tools to help scientists store, analyze, and share data from high-throughput experiments and observational studies. The Fred Hutchinson Cancer Research Center uses CPAS to …

In Part 1 of this article series, we looked at how the Falcon transactional storage engine was architected and how it compared to some of the other MySQL storage engines. In this article, I?ll focus on how Falcon performs transaction management, including some special points on where Falcon differs from some of MySQL?s other transactional engines.

As of MySQL 5.0 there is no SHOW CREATE TRIGGER which is pretty annoying. I don’t like using “show triggers like
“, so I figured I’d write a wrapper around mysqldump. For the record, this was a huge pain the ass. I did this on Fedora, GNU sed version 4.1.5. You need to have your password stored in ~./my.cnf for this to work, I believe. I haven’t tried it without it.


mysqldump -dnt database | sed "/\/\*\!4.*\*\/;*/d" | sed "s_/\*\!5[0-9]*__g" | sed "s_DEFINER=.*\*/__g" | sed "s/\*\/;*//g" | sed "/SET/d" | sed "s/^[ \t]*//" | sed "s/\ \ */ /g" | sed "/--/d"


You will get a dump of ALL the triggers in your database, using this. However, since that’s what I need on this particular example, it’s what I’m sharing. I’m sure I could have cleaned up the code a little and used fewer calls to sed, but frankly I don’t mind, since it works fine.

I hope this helps someone.

If you're in the L.A. area, this weekend I will be speaking at the Southern California Linux Expo (SCALE) on SQL coding, schema and index tuning MySQL servers. Come meetup with me at the MySQL BoF or find me around in the sessions.

The third speaker in the spotlight series is Joe O'Brien, who, as it so happens, is the only other speaker than myself who lives in Columbus, Ohio. Joe is a principal at EdgeCase Consulting, a web design and development firm focusing fairly heavily on enterprise and web applications built with Ruby (on Rails).

Joe is teaching a 3 hour tutorial on Monday called "Vital Rails: An Introduction to the Rails Framework". The tutorial promises to be one of the most popular ones, as Ruby, and Rails in particular, is always a highly requested conference topic. Joe will be covering the Rails framework, with a focus on ActiveRecord, the framework's critical component for accessing and updating data in the database using the, uh, ActiveRecord …

I find it funny that in the middle of winter in Sweden that MySQL's
server farm requires both air conditioning and an open window!

Notice the excellent Swedish engineered racks :)

It's quite an effort to compile and test 3 versions of MySQL on 4 different machines, but that is what I have done for the first binary distribution of the PrimeBase XT pluggable storage engine.

Of course, its worth the effort because this is the "holy grail" of the pluggable storage engine strategy. Namely, binary plug-ins that work with the binary distributions prepared by MySQL and others in the community.

And by creating an installer script I have made it easier than ever to install the plug-in. So after you have downloaded the binary package from http://www.primebase.com/xt, all you have to do is:

1. Start your MySQL server.

2. Enter: sudo ./install

The installer will automatically determine the version of the server running and install the corresponding plug-in.
