New PEAR release: CodeGen_MySQL_Plugin

I have just released CodeGen_MySQL_Plugin 0.1.0dev

This package has been around in PEAR CVS for quite a while, now it is finally seeing its first alpha release.

Starting with the upcoming 5.1 release MySQL will provide a general plugin interface within the MySQL server.
Up to MySQL 5.0 the only way the MySQL server could be extended without recompiling it was to add UDF modules that provide new user defined functions on the SQL level. The new generic plugin interface allows for different kinds of plugins to be implemented on top of it.

Currently the plugin interface supports the follwing kind of plugins:

  • "daemon" plugins that only hook into server startup and shutdown
  • fulltext parser plugins that change the way data is broken into words for fulltext indexes
  • storage engine plugins

We will talk about MySQL Replication and we will see some of the advanced techniques. We will set up basic, circular and multi-master replication on the fly, for those of you who are not yet familiar with this technology.

There are also hints, tips and tricks for advanced users and DBAs, with suggestions on hardware, storage engines and performance considerations, plus real examples from some big names - Yahoo, Flickr and Wikipedia to name few.

MySQL Archive Tablespace for FACTs

I’m visiting a Pentaho customer right now whose current “transaction” volume is 200 million rows per day.  Relatively speaking, this puts their planned warehouse in the top quintile of size.  They will face significant issues with load times, data storage, processing reliability, etc.  Kettle is the tool they selected and it is working really well.  Distributed record processing using Kettle and a FOSS database is a classic case study for Martens scale out manifesto

This organization doesn’t have unlimited budget.  Specifically, they don’t have a telecom type budget for their telecom like volume of data.  One of the issues that has come up with their implementation has been the tradeoff between space, and keeping the …

New XAMPP version for Linux and Windows

After two months of hard work we are proud to announce a new release of XAMPP for Windows and Linux. New in both releases of XAMPP are MySQL (5.0.37), PHP (4.4.6), phpMyAdmin (2.10.0.2), and OpenSSL (0.9.8e). The Windows version also contains up-to-date versions of: FileZilla FTP Server (0.9.23), ADOdb (4.94), and Zend Optimizer (3.2.4).

With XAMPP 1.6.1 we tried to make the Windows version ready for Vista. The beta tests were very successful and most people reported a very smooth XAMPP under Vista but there were also people still having problems. Please get in touch with me if you also encounter problems on Vista. Currently please avoid installing XAMPP into the "Program files" folder.

Heading off to the MySQL Conference


After some long months of intensive bug fixing, it's time to pack up the stuff and head off to the MySQL Conference & Expo. Since this is actually my first MySQL (User's) Conference, it's bound to be interesting.

We've got a full schedule here, so it will definitely not be boring.

Monday, April 23, 8:30am - 5:00pm, Ballroom D (with lunch 12:00am to 1:30pm). Lars, JDD and I am going to hold a replication tutorial for a full day where we'll go over some basics on how to set up replication to work properly, but also delve into some advanced stuff like row-based replication and cluster replication to …

A lot of updates to the AWS S3 storage engine

Sarah McLachlan & MySQL

I haven’t updated my blog in a while, so as a temporary placeholder, I’ve decided to just post a random conversation where I attempt to rewrite Sarah songs into either programming languages or pseudo code. Dorky, at best.

(23:27:29) esofluffy: so if you were to be listening to Sarah McLachlan, which song would you choose?
(23:27:39) arcology88: umm
(23:27:43) arcology88: the silence
(23:27:44) arcology88: haha
(23:27:49) esofluffy: I think I’ll go for “Hold On”
(23:28:09) esofluffy: well, instead i went for “Building a Mystery”
(23:28:19) esofluffy: I want to rewrite the song to be different.
(23:28:31) arcology88: hehe
(23:28:32) arcology88: explain
(23:29:00) esofluffy: well, first of all I’d rename it… to “Parsing a SQL_TREE”
(23:29:28) esofluffy: “cuz you’re working… on Parsing a SQL_TREE”
(23:30:26) arcology88: ahhah

Nested-loops join speedup idea promoted to WL task

The idea how to speed up nested-loops join a little I've mentioned earlier has now been promoted into a worklog entry. It is now known as WL#3724 "Short-Cutting Join Execution: Speeding up star queries" and its text is publicly available at MySQLForge.

At the moment there is only a short description, but hopefully Martin Hansson (the assigned developer) will add more content there.
