A small army of Facebook MySQL experts will be converging on Santa Clara, Calif. next week where several of them are leading sessions at the Percona Live MySQL Conference and Expo. I had the chance to chat …

A few weeks ago I wrote about “MySQL Performance at High Concurrency” and why it is important, which was followed up by Vadim’s post on ThreadPool in Percona Server providing some great illustration on the topic. This time I want to target an opposite …

How InnoDB performs a checkpoint
+7 Vote Up -0Vote Down

InnoDB’s checkpoint algorithm is not well documented. It is too complex to explain in even a long blog post, because to understand checkpoints, you need to understand a lot of other things that InnoDB does. I hope that explaining how InnoDB does checkpoints in high-level terms, with simplifications, will be helpful. A lot of the simplifications are because I do not want to explain the complexities of how the simple rules can be tweaked for optimization purposes, while not violating the ACID guarantees they enforce.

A bit of background: Gray and Reuter’s classic text on …

I want simple things to be easy
+1 Vote Up -1Vote Down

I like to write tools that make hard things easy, when possible. By and large, MySQL is easy and simple. But some simple things are too hard with MySQL. I want to change that, at least for the things that matter the most to me, and which I think I know how to fix.

I will probably write a lot about this. I have already written a number of rants blog posts about the lack of instrumentation in MySQL, and that is where I’ll probably continue to put most of my energy.

To begin with, imagine this simple scenario. You are a remote DBA. Your client says “New Relic is showing periods of slow response time from the database.” You connect to …

Eben Moglen says EC case against Oracle-Sun is flawed. The value of open source. And more.

Can't wait for table change logs.
+0 Vote Up -0Vote Down

At today's keynote by Mark Callaghan one of the new options he talked about are table change logs. He mentioned they might be of use to external applications, like Flexviews, which he mentioned but not directly. He asked if the guy who wrote it was in the audience, so I got to wave my hand and yell 'Flexviews!'.

I caught up with Mark at the Facebook party this evening. I had a chance to talk to him not only about the change logs, but also about Kickfire and the SQL chip. He asked me what I thought about working at Kickfire and I smiled and said I love it. I think I said "I've never been able to join a billion row table to a hundred million row table, sort, group and get …
