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.

For MySQL …

Last Thursday (September 17, 13:00 UTC), Lars Thalmann explained the Architecture of MySQL Backup. Lars is leading the MySQL Replication & Backup teams, and has given several MySQL University sessions before.

I was on sick leave last week and forgot to announce this session - sorry!  However, since the session was recorded (video & audio), you can listen to it anytime. Please find the recording and the presentation slides on this 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.

Before I even start this post I am going to repeat our view that Oracle is well aware that it has little to gain from killing off MySQL and that we expect MySQL to become the scale-out database for non-transactional web applications and to compete with SQL Server in departmental deployments.

That said there has been some interesting discussion on Twitter this week in response to the European Commission’s investigation of Oracle-Sun about whether Oracle could - in theory - kill off MySQL. Here’s a Q+A explaining my view as to how Oracle could kill MySQL but probably won’t, and why MySQL AB’s choice of dual licensing and the GPL has come back to haunt Monty Widenius.

Q. Oracle can’t kill MySQL even if it wants to, because its open source. Right?

In line with my prediction from few days ago, Larry Ellison is announcing the new Database Machine — the new version is targeting OLTP workloads and is based on Sun hardware.

Looks like I just got the date wrong. Oh well, now is the announcement, hype and demo is at the Oracle Open World and shipments are to start upon Oracle-Sun acquisition completion.

So what’s new in Exadata that I …
