MySQL 5.4 was released this week at the MySQL conference, and billed as the “community release.” This seemed odd to some of us, and I heard lots of comment on it in the hallways. After all, the release was a surprise; the community didn’t know it was happening. A source from within Sun, who is familiar with the details and wishes to remain anonymous, told me the story behind the release.

The slides for my session on Maatkit at the MySQL Conference are uploaded. They should appear on the speaker presentation files page, but I have heard that it can take a few days. Please let me know if they’re not there by May 1, 2009. I did not have time to plow through everything in the slides. (I deliberately prepared more material than I could cover, and just stopped when I ran out of time.

Today I attended the Drizzle Developer Day which took place in the auditorium of the Sun Campus in Santa Clara.

Many of the the Drizzle core hackers as well as several other people interested in the development attended this event, hacking away and discussing various issues. Jeremy Zawodny gave a presentation about Craigslist's needs for Drizzle, Jay Pipes gave an overview over Google's protocol buffers library. I took a number of pictures, which you can find in my …

I am pretty happy with how the MySQL User Conference developed, considering the announcement earlier in the week. As I have blogged before, I don't mind working for a database company, that's where I have my roots (or root as in -u root) after all. I actually saw very few effects of the announcement during the whole week.

Both talk I did, on libmysqld and on HA with MySQL together with Robert Krzykawski, went very well. The first had a small, but interested, audience, the latter was pretty full with people that also seemed interested. Robert did a stellar job of presenting what …

We at Tag1 have used the Cacti Memcache templates many times. (http://dealnews.com/developers/cacti/memcached.html) They have become a staple for us and many others. However, we and one of our clients have had issues making them work for monitoring multiple Memcache instances (running on different ports) on the same host. It is possible to make this work with the vanilla templates, but it is a bit difficult.

At the MySQL Conference & Expo 2009, I did a presentation "Mastering the Art of Indexing" , and now you can get the slides from MySQL Conference site .
I was excited that so many people attended to my session. I hope the session will help you to improve indexing techniques. Feedbacks are welcome.

I was asked from some people at the conference where my blog is. I am mostly publishing MySQL technical information in Japanese, but now I believe it's a good time to start publishing in English. I plan to post mainly benchmarking & performance analysis, high availability solutions, internationalization (which sometimes people have problems), etc.

It's interesting that just as Apple announced surprisingly positive quarterly results, Microsoft announced their first decline in sales revenues in 23 years.  While Microsoft is not in any kind

Now that it's Friday, I can finally come up for air and say that both the MySQL and Percona Conferences (which I wrote about earlier) surpassed my expectations. Having the two going on semi-concurrently worked out pretty well. At no time did I find myself without at least two sessions I wanted to see. Often times I had to really cut lunch short to make sure I didn't miss anything.

Other MySQL Conference veterans I asked has very similar responses.

There's a ton of other stuff to digest, and I hope to write up some thoughts in the coming days and weeks.

As usual, a big part of the conference for me was being able to meet up with people I don't see often or who I've never met face to face. Meeting up with people solving similar problems at places like Facebook, Google, Mixi, and other high-traffic sites is invaluable.

This is the 143rd edition of Log Buffer, the weekly review of database blogs.

So . . .  Anything happen while I was away?

Okay, so I heard the big news. And just in case you haven’t, here it is from Sheeri Cabral: Oracle Buys Sun. This is a sea-change in the hi-tech world, and the DB part of it will also get rocked, Sun being the home of MySQL. There’s lots of comment in Sheeri’s post, and indeed, all over the database blogging world. I will try here to cover the best of it.

Oracle + Sun + MySQL
