MySQL Camp 2007
+0 Vote Up -0Vote Down

I caught most of the second day of MySQL Camp 2007. It was fun and educational as before. The format was a little different than the last Camp; everything was in one room. Google and Proven Scaling provided food.

Sessions were loosely organized, to say the least, but that’s what an un-conference is [...]

MySQL Toolkit version 815 released
+0 Vote Up -0Vote Down

I've just released changes to all tools in MySQL Toolkit. The biggest changes are in MySQL Table Sync, which I'm beginning to give sane defaults and options to. Some of the changes are incompatible (but that's what you get with MySQL Table Sync, which is still very rough). I also found and fixed some bugs with MySQL Visual Explain. Thanks to everyone who submitted bug reports.

Note, the formatting overflow in MySQL Query Profiler was not a security vulnerability. It was simply an issue with a Perl formatting code that displayed numbers as hash marks when they got big enough.

Introducing MySQL Visual Explain

If you've ever wished you could see MySQL's EXPLAIN output formatted as a tree, now you can. MySQL Visual Explain transforms EXPLAIN output into a hierarchical view of the query plan, which is significantly easier to read and understand.

MySQL Toolkit version 675 released
+0 Vote Up -0Vote Down

I've just released changes to two of the tools in MySQL Toolkit. MySQL Table Checksum got some convenient functionality to help you recursively check slaves for bad replicated checksum chunks. MySQL Archiver got statistics-gathering functionality to help you optimize your archiving and purging jobs, plus a few important bug fixes.

MySQL Toolkit distribution 620 released
+0 Vote Up -0Vote Down

MySQL Toolkit distribution 620 updates documentation and test suites, includes some major bug fixes and functionality changes, and adds one new tool to the toolkit. This article is mostly a changelog, with some added notes.

Many of the tools have matured and I just needed to make the documentation top-notch, but there's still a lot to be done on the crucial checksumming and syncing tools. Time is in short supply for me right now, though. In fact, I actually finished this release on June 22, but wasn't able to release it till just tonight!

Why I write Free Software

Brian Aker was a recent guest on the LinuxCast podcast with Don Marti. Brian has some interesting thoughts in this podcast and elsewhere on his blog, on motivations for writing Free and/or Open Source software. Here's why I do it myself.

Archive strategies for OLTP servers, Part 3
+0 Vote Up -0Vote Down

In the first two articles in this series, I discussed archiving basics, relationships and dependencies, and specific archiving techniques for online transaction processing (OLTP) database servers. This article covers how to move the data from the OLTP source to the archive destination, what the archive destination might look like, and how to un-archive data. If you can un-archive easily and reliably, a whole new world of possibilities opens up.

A challenge: partition a character set in MySQL

How good are your SQL and/or general coding skills? I have a specific challenge I'd like your help solving. I am not sure it's possible, but I'd love to be proven wrong.

MySQL Archiver 0.9.2 released
+0 Vote Up -0Vote Down

This release fixes some minor bugs and adds a plugin mechanism. Now you can extend MySQL Archiver with your own code easily. You could use this to run setup and tear-down, hook code into the archiving process, and more. Possibilities include building summary tables in a data warehouse during archiving, handling dependencies such as foreign keys before archiving each row, or applying advanced logic to determine which rows to archive.

MySQL Archiver 0.9.1 released
+0 Vote Up -0Vote Down

MySQL Archiver is the implementation of the efficient forward-only archiving and purging strategies I wrote about more than a year ago. It nibbles rows from a table, then inserts them into another table and/or writes them to a file. The object is to do this without interfering with critical online transaction-processing (OLTP) queries.
