The latest from the MySQL community

It's that time of the year where MySQL would be speakers are called to action. As usual, the main event is the MySQL spring conference, this year hosted by Percona. The call for participation to the MySQL Conference And Expo 2012 is still open until December 5th. To submit a proposal, you should register as a speaker and then fill in the form.
There is a conference committee which is already busy evaluating the proposals that have been submitted so far. The committee is demanding (I know for a fact, since I am in it!) and therefore, if you want to submit something, be very critical with yourself and polish your …

Some of you may be aware that MySQL is increasingly using an Oracle-internal bug tracker. You can see these large bug numbers mentioned alongside smaller public bug numbers in recent MySQL release notes. If you’re particularly unlucky, you  just get a big Oracle-internal bug number. For a recently fixed bug, I dug further, posted up on the Percona blog: http://www.mysqlperformanceblog.com/2011/11/20/bug12704861/

Possibly interesting reading for those of you who interested in InnoDB, MySQL, BLOBs and crash recovery.

There's now 2 weeks left of the Call for Papers for Percona Live MySQL Conference and Expo (Santa Clara, CA). This weekend I've been finalizing my abstracts for submission and I trust many of you are doing the same. (If nothing else, do it for the free entrance! Or because you're passionate about MySQL, yeah, that's what I meant...)

This is the main annual MySQL event, so I thought it is worth the bandwidth to use these two weeks for some discussion and brainstorming. We are the MySQL community, it's up to us to make this a great conference now! This year I'm on the program committee, so I'm looking forward to reviewing many, many great proposals. At the same time, I'm interested to hear what you, dear readers - and hopefully future conference visitors - are interested in seeing at the conference? I'll share my ideas here and you can share yours in the comments …

Part of my job at Percona is to perform customer audits.  I’ve had fun the last week getting up to speed on some of the great tools in the Percona Toolkit.  I’m sure people have talked about these before, but to be honest, I always found it hard to take the time to learn new tools, and at my previous job there were often a lot of tools in-house that made it easier to avoid learning something new.  The great thing about the Percona tools is that they aren’t environment dependent (as much as is possible), they typically only require Perl to run.

So, with that being said, I wanted to just go through a few of the tools I learned about this last week that I found useful.

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 …

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.

Last week was a bumper week in London for MySQL users, DBAs & developers. We had the Oracle MySQL Developer Day and Percona Live London 2011. Both events were sold out, bringing in a good 300+ people to each event. From what I could tell the crowds were quite unique, so thats a good 600+ people interested in MySQL in London. The death and unpopularity of MySQL is greatly exaggerated.

At Oracle’s event, we naturally only had Oracle presenters. There was Simon Deighton (Sales Manager), Tony Holmes (Sales Consultant), …
