This Thursday (February 11th, 14:00 UTC), Seppo Jaakola & Alex Yurchenko will talk about MySQL Galera Multi-Master Replication. Galera provides synchronous multi-master replication and uses a certification-based replication method for replicating transaction write sets in a DBMS cluster. The replication method requires close co-operation with database transaction processing and DMBS must support a specific replication API to be compatible with Galera. Codership has integrated Galera replication in the InnoDB storage engine, and the resulting MySQL/Galera cluster product has been published as a production-ready GA release in December 2009. The MySQL/Galera release 0.7 is available on the Codership and Launchpad sites.

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 tentative list of upcoming sessions:

• February 18: Performance Schema: Instrumenting Code (Marc Alff)
• February 25: Securich - Security Plugin for MySQL (Darren Cassar)
• March 4: MySQL Column Databases (Robin Schumacher)
• March 11: Improving MySQL Full-Text Search (Kristofer Pettersson)

By the way, did I mention that we need more speakers to fill up the 2010 schedule? If you'd like to be a speaker, have a look at this blog article!

I may sound like a broken record, but currently we have only three MySQL University sessions scheduled for this year. In 2009, we ran more than 25 sessions, and I'd surely like to get anywhere near that figure.

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 sessions' 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:

This Thursday (October 22nd, 13:00 UTC), Walter Heck will present Dual Master Setups With MMM. MMM (Multi-Master Replication Manager for MySQL) is a set of flexible scripts to perform monitoring/failover and management of MySQL master-master replication configurations (with only one node writable at any time). The toolset also has the ability to read balance standard master/slave configurations with any number of slaves, so you can use it to move virtual IP addresses around a group of servers depending on whether they are behind in replication. For more information, see http://mysql-mmm.org/.

This Thursday (October 15th, 13:00 UTC), Giuseppe Maxia will present the Spider Storage Engine. Here's from the abstract: Everybody needs sharding. Which is not easy to maintain. Being tied to the application layer, sharding is hard to export and to interact with. The Spider storage engine, a plugin for MySQL 5.1 and later, solves the problem in a transparent way. It is an extension of partitioning. Using this engine, the user can deal transparently with multiple backends in the server layer. This means that the data is accessible from any application without code changes. This lecture will briefly introduce MySQL partitioning, and then show how to create and use the Spider engine, with some practical examples. The talk covers the latest version of the Spider engine, which includes a condition pushdown feature that increases performance significantly.

This Thursday (October 8th, 13:00 UTC), Jörg Brühe will give a talk on Building MySQL Releases on Unix. Jörg will describe the tools used by the MySQL Build Team for release builds on Unix-style platforms, and present a script to simulate the essential parts of that process locally on a developer's home machine. He works at the MySQL Build Team, so you can expect in-depth insights and instructions.

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.

This Thursday (September 24th, 14:00 UTC), Heikki Tuuri, the father of InnoDB, will give a session on Concurrency Control: How It Really Works. He'll describe how InnoDB manages concurrency control, so that the system protects data integrity. Beginning with the basics of transaction management, Heikki will include a discussion of the ACID (atomicity, consistency, isolation, and durability) properties, and explain various transaction modes, locking, deadlocks, and more advanced topics such as the impact of next-key (gap) locking, referential integrity, XA (distributed transaction management) support, and more. While the discussion will focus on the InnoDB implementation, many of the concepts presented apply to other database systems and storage engines.
