MySQL University: InnoDB File Formats and Source Code Structure

This Thursday (October 1st, 14:00 UTC), Calvin Sun will give a session on InnoDB Internals: InnoDB File Formats and Source Code Structure. The InnoDB storage engine provides transactions, row-level locking, and automatic crash recovery. Its on-disk files play a pivotal role for those key features. This presentation describes how on-disk files are structured, how compressed tables are organized, and how long variable-length columns are stored. As we develop new features, it is inevitable for file format changes. We will explain how the new file format management works in the InnoDB Plugin.This talk also covers InnoDB source code structure.

For MySQL University sessions, point your browser to this page. You need a browser with a working Flash plugin. You may register for a Dimdim account, but you don't have to. (Dimdim is the conferencing system we're using for MySQL University sessions. It provides integrated voice streaming, chat, whiteboard, session recording, and more.) All MySQL University sessions are recorded, that is, slides and voice can be viewed as a Flash movie (.flv). You can find those recordings on the respective MySQL University session pages which are listed on the MySQL University home page.

MySQL University is a free educational online program for engineers/developers. MySQL University sessions are open to anyone, not just Sun employees. Sessions are recorded (slides and audio), so if you can't attend the live session you can look at the recording anytime after the session.

Here's the schedule for the upcoming weeks:

  • October 8: Building MySQL Releases on Unix (Jörg Brühe)
  • October 15: The Spider Storage Engine (Giuseppe Maxia)
  • October 22: Dual Master Setups With MMM (Arjen Lentz)
  • October 29: MySQL scalability on SPARC & INTEL X5500 (Nehalem) (Benoit Chaffanjon)
  • November 12: Gearman for MySQL (Giuseppe Maxia)
  • November 19: memcached Functions for MySQL (UDFs) (Patrick Galbraith)
  • December 3: Practical Full-Text Search in MySQL (Bill Karwin)

The schedule is not engraved in stone at this point. Please visit http://forge.mysql.com/wiki/MySQL_University#Upcoming_Sessions for the up-to-date list. On that page, you can also find the starting time for many time zones.

MySQL University: Speakers wanted!

We'd like to fill the remaining session slots for MySQL University this year. Currently, there are 7 available slots in 2009, as can be seen here:

http://forge.mysql.com/wiki/MySQL_University#Upcoming_Sessions

Anyone who has something technical to say about MySQL qualifies as a speaker. MySQL University sessions take place on Thursday afternoons European time, and normally have between 20 and 30 attendees, but quite a lot of people listen to the recordings when the live session time isn't convenient for them. We're using Dimdim as our conferencing system, so the setup for speakers is very simple: Just grab a headset, start a Flash-enabled browser on either Windows, Mac OS X, Linux, or Solaris, perform a 10-minute test with the MySQL University host, and you're ready for the live session. Everything is done through the browser, so you don't even need a telephone.

So it's very simple to be a speaker, but what should you talk about? Well, maybe you already have an interesting topic suggestion (or, even better, a set of slides you can reuse), but you can also have a look at topics suggested by attendees:

MySQL University sessions are open to anyone, not just Sun employees. Sessions are recorded (slides, audio, and desktop sharing), so if you can't attend the live session you can look at the recording anytime after the session.

Please suggest your session(s) to Stefan Hinz (stefan.hinz@sun.com), and let me know what date and time of the day would be best for you!

About

mysqlf is a common typo on the #docs IRC channel of the MySQL documentation team. It shows a high (some might say, dangerous) degree of identification with MySQL. Trying to pronounce it will probably result in tongue injuries.
