Thanks Percona and attendees for a great Percona Live UK 2011

Many people have asked me what do I think was the best thing about Percona Live UK. I always answered: that it happened in the first place! This was the first time we had such a large and high-quality MySQL conference in Europe, and many well known bloggers and speakers that can't always travel to Santa Clara were present.

More importantly, many MySQL users who don't travel to Santa Clara could now see them speak and meet with them. I met at least 4 hard core MySQL DBA's from Helsinki that I've never met before. We had to travel to London to meet each other! (But if you are in Helsinki, we have our first MySQL user group tomorrow, this should fix things!)

When I walked into the conference venue, I introduced myself to a person that stood there talking to Baron Schwartz. He introduced himself as Schlomi Noach. Then we started laughing: we know each other quite well, Schlomi and I run the annual MySQL awards as co-secretaries. I never realized we had not met in person before!

The content of the program was very high quality. In the past few years I've come to value informal one-to-one discussions as my primary source of new information instead of the official lectures, but at this conference I actually chose to attend as many talks as possible and learned new information from many of them.

Galera 1.0 is here, Severalnines support, more to come

There are moments in history that become like signpost that everyone remembers the rest of their lives. Like where were you when you heard the news that JFK had been shot, or those 9/11 planes hit the WTC twin towers. If you work with MySQL and high-availability, then this week will be remembered as such. And if you're a European MySQL geek, you will remember that we were at the Percona Live UK conference when Galera clustering 1.0 was announced. Btw, the conference itself was also historical, at least for European MySQL users. I will have to write a separate blog post about the conference, because it was a great one, and I have to post slides of my 2 talks too. But this blog post is dedicated to the stable release of Galera.

Helsinki MySQL User Group, Tue Nov 1 @ 18:00

Suomeksi: MySQL käyttäjätapaaminen Helsingissä 1. marraskuuta. Klikkaa allaolevaa linkkiä ilmoittautuaksesi, siellä saat myös lisätietoa suomeksi.

Finally it's here! So many of you have always asked about it. Markus and other Elisa guys. Osma and Ilkka at Habbo Hotel. And others... MySQL was born in Helsinki, InnoDB was born in Helsinki, a lesser known database / also MySQL engine called Solid was born in Helsinki, and 2 great replication companies, Continuent with multiple generations of clustering for MySQL, and Codership with Galera, are Helsinki companies. And amidst this embarrassment of riches, what did we not have?

A MySQL User Group.

MySQL HA shootout at Percona Live UK

I'm looking at the schedule for Percona Live UK coming up in 2 weeks from now and realize there's quite a smorgasbord of High Availability talks. What's more interesting, I see that we will be presenting some opposite opinions for the audience to digest:

Upcoming conferences: Highload++ Moscow and Percona Live London

Update: I won't be in Moscow after all. I was denied visa on grounds that my passport is beginning to fall apart and there wasn't time to get new passport, invitation and visa. Maybe next year - I was excited to go.

October brings 2 very interesting conferences. I will be speaking first on Oct 3rd at HighLoad++ in Moscow and a few weeks later on Oct Oct 25 at Percona Live in London. I will give a talk called Choosing a MySQL Replication / High Availability Solution which is based on my thinking developed in my recent blog post The ultimate MySQL high availability solution and many benchmarks and functional tests I've done while evaluating these technologies.

At Percona Live I will also give a second talk Fixed in Drizzle: No more GOTCHA's. It looked like none of the Drizzle core team would be able to attend the conference and as I was going to be there I volunteered to cover a Drizzle topic at the same time. This is a talk Stewart Smith has given a few times at earlier conferences which I liked and proposed to Percona. As it turns out, also Stewart will be in London after all, so there will be 2 Drizzle talks, I will still give the one I'm committed to.

Things I've said about Mårten Mickos

In July I wrote a blog post MySQL community counseling: talking about your feelings. It was triggered by an earlier blog post and followup threads on Google plus by Monty Taylor, Andrew Hutchings, etc... (everyone involved in that outburst have apologized and moved on long ago). I wanted to use that opportunity to highlight what I call our hidden trauma related to the Oracle acquisition of Sun, things that I still hear being discussed today, 2 years later, and things that I consider unresolved or unsolved that I see causing friction and misunderstandings - the kind of which that outburst too represented. Both before and after writing it I wondered if it was a good idea to publish it - I wondered whether I would be seen as helping to solve the problem or just contributing to it. I actually got some positive feedback about it, including from people at Oracle/MySQL (it's kind of a defense of Oracle, actually) so perhaps it wasn't all wrong. Thanks for that feedback by the way, it was really valuable to me.

A part of that post mentions three persons by name: Mårten Mickos, Zack Urlocker and Kaj Arnö. The post in general is not about any of them and they appear mostly as historical MySQL figures, while the post is about the current situation in the MySQL community and in particular how we are still dealing (or not dealing) with events related to the Oracle acquisition. Each of them appear only in a few sentences. Perhaps that brevity is also part of the problem, as you'll see, this post certainly will not be too short. But nevertheless, if you happen to focus on those specific sentences instead of the rest of the post, they do read as quite grave accusations against these persons - perhaps more than any others against Mårten.

Which is also a bit ironic, because whenever I have talked in private conversations about Mårten's open letter to Neelie Kroes, I always had only good things to say about him:
