Here are some random thoughts, notes, observations, etc.

Jay Pipes - he made the conference possible

• Friendster uses Bugzilla internally. Yes they’re still alive, even though MySpace and so forth are around and kicking. Had to Google them (I wanted to find their old talk about their storage engine), and found MySQL Customers - Friendster, instead. From 2005, Dathan’s (now at Flickr) presentation. Never did find the storage engine stuff, beyond random bits in the press.
• Probably the best blog post that hit Planet MySQL, as opposed to the session summaries and so on, comes from …

NOTE: Problems presently exist, I’m seeking the expert help of the community and Perl Gurus

I have the need to do some quick benchmarking, I use MyBench as it’s effective in being able to plug in a query, some randomness and 2 minutes later (with a correctly configured Perl/MySQL environment) you have multi-threaded load testing.

However, when the environment you are on is not configured, and you only know the basics for Perl Operation and Installation, (code is just code, that’s the easy part) and the box is not accessible to the outside world say for cpan, it gets more complicated. I’ve attempted to install and configure DBI, DBD::mysql and …

MySQL's version-specific conditional comment syntax confused me for the longest time. Then I learned about printf formatting rules, and it all became clear. Read on if you don't already know what I mean.

Mark Shuttleworth on software patents: Microsoft is not the real threatThe real threat to Linux is the same as the real threat to Microsoft, and that is a patent suit from a person or company that is NOT actually building software, but has filed patents on ideas that the GNU project and Microsoft are equally likely to be implementing.Interesting thought... and actually, not just a thought: Microsoft alumnus Nathan Myhrvold is busy accumulating patents with his Intellectual Ventures company. There's more like that around...

I'm thinking... perhaps money (greed, that is) will solve this problem after all. These companies have nothing else going on except to try and arrange licensing deals. And thus companies producing a lot cash (big licensing potential) will be the prime targets. And, funnily …

Dealing with dumping and recovery of large and partially corrupted database I’ve got couple of feature ideas for mysqldump or similar tool and appropriate import tool

Dump in parallel single thread dump is not efficient of course especially on systems with multiple CPUs and disks. It is lesser issue in recovery case because import takes most of the time anyway but will be handy for some backup needs.

Dump each table in its own file This is much more convenient compared to single say 100GB sql file allowing to prioritize data load and if load fails for any reason you can easily restart it. Also it allows to prioritize data load if you’ve got to load many tables which have different priority for your application.

Safe Dump Dumping corrupted Innodb tables you will have some of the them crashing Innodb which breaks mysqldump process. It would be great for load script to …

I have not had a serious Innodb corruptions for a while, typically even if it happened it was some simple table related corruption which was easy to fix on table level. In couple of cases during last year when it was more than that we had backups and binary logs which means it was easier to recover from backup and replay binary logs.

This time I have a challenge to play it hard way because backup is in special form which will take a while to recover. It also should be nice exercise in patience because database is over 1TB in size.

One bug I already reported makes me worry. If it is global bug it should have been Innodb recovery show stopper while it goes back so many releases (5.0.33 surely still has it).

Lets see what else we run into.

One minor “practicality” I should mention is using –socket=/tmp/mysqlx.sock –port=3307 or something …

I have been very busy this past months, with both personal crisis and mega-patches. This is my MySQL blog so lets keep it to topic.
A couple of weeks ago, the plugins mega-patch was finally pushed and was released to the world in version 5.1.18. Thanks to Ingo and Sergei for keeping up the effort while I was occupied. As part of the code push, InnoDB code was stripped out of the main mysqld code and stored where it belongs, within Innobase's code. This is an exciting development as it now makes it easier than ever for plugin developers to create plugins without having to modify any existing code within mysqld. It has taken many months to get to this point but we are finally there. Anyone remember our CEO announcing the plugin initutive back when Innobase was acquired by Oracle? October 2005, I believe.

Since that push, I am back on bug-fixing... I have an annoying bug on Itanic with Intel's Itanic Compiler. (Yeah, I know the …

During JavaOne this year Rags and I did a hands on lab on DTrace. The topic was "Using DTrace on Java and other Web 2.0 Languages in Solaris". Due to some unforeseen reason the lab was scheduled from 8:45 PM to 10:45 PM (Yes PM) and that to on the day of the big party at JavaOne. So I was expecting to be speaking to an empty room but lo and behold we had close to 100 engineers ( a few pretty drunk) and most stayed until the finished the lab.It was pretty heartening and was worth all the efforts that went into …

Ssst! I'm currenty in Stockholm, Sweden, delivering the MySQL 5.1 Cluster Certification Exam on MySQL's very own Cluster summit.

At the OSBC conference, SnapLogic, a new open source company focused on data integration networks, will be showing their stuff.  It's pretty cool technology.  Think of it as Enterprise Application Integration (EAI) meets Yahoo! Pipes.  You have to see the demo to really appreciate how much they have simplified the complexity of integration.  The company includes some serious talent and brings a very modern network approach to solving the enterprise integration problem.
