Drizzle Day 2012

Henrik has already posted it over on the Drizzle Blog, but I thought I’d give a shout out here too.

We’re holding a Drizzle Day right after the Percona Live MySQL Conference and Expo in April. So, since you’re all like me and don’t book your travel this far in advance, it’ll be easy to stay for the extra day and come and learn awesome things about Drizzle.

I’m also pretty glad that my employer, Percona is sponsoring the event.

Information on Bug#12704861 (which doesn’t exist in any public bug tracker)

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.

Speaking at Percona Live London 2011 (on Drizzle!)

Both Henrik and myself will be at Percona Live London 2011 in late October speaking on the wonderful Drizzle database server.

Other speakers at the conference will be talking about a wide range of topics surrounding the MySQL ecosystem including performance monitoring, backup, search, scaling and data recovery.

P.S. I do have a discount code – ask me in the comments for it!

Speaking at OSCON

OSCON is coming up again: July 25th-29th in wonderful Portland, OR. If you come to OSCON, not only will you be at OSCON, but you’ll be in Portland in July – which is just lovely. We’ll also have other people from Percona there and it should be a great lot of fun.

So come along and talk interesting technology – I’ll be speaking on “Dropping ACID: Eating Data in a Web 2.0 Cloud World“. If you know my love of reliable software with known failure modes, you’ll probably enjoy this one – especially if you saw my “Eat My Data: How everybody gets POSIX file I/O Wrong” which when given at OSCON 2008 was given to a packed room with people in the aisles and out the door.

Speaking has its pluses and minuses of course. It takes a very, very long time to construct a good talk (I would guess 12hrs for each hour of speaking) and you do miss out on some other sessions (preparing, going over, final touches, rehearsals). It is rather rewarding though, and sparks very interesting conversations afterwards.

I should also mention, if you want 20% off OSCON rego: use os11fos as discount code.

xtrabackup bazaar repositories upgraded to 2a format

I have just upgraded the xtrabackup bazaar code repositories to the 2a format. This means that bzr 1.16 is required to access the source code repositories now.

If you get an error like the one below when working with a local branch, you’ll need to run “bzr upgrade” in it (see below for example). For branches on launchpad, you can use the web UI and hit the “upgrade branch” button.

stewart@willster:~/src/percona-xtrabackup$ bzr pull
Using saved parent location: bzr+ssh://bazaar.launchpad.net/%2Bbranch/percona-xtrabackup/
Doing on-the-fly conversion from RemoteRepositoryFormat(_network_name='Bazaar repository format 2a (needs bzr 1.16 or later)\n') to RepositoryFormatKnitPack1().
This may take some time. Upgrade the repositories to the same format for better performance.

Joining Percona

As you may have read on the MySQL Performance Blog post – I’ve recently joined Percona. This is a fairly exciting next step. I’ll be in New York for Percona Live next week, where I’ll be giving a session titled “Drizzle 7, GA and Supported: Current & Future Features”.

I’ll write more soon, there’s a lot keeping me busy already!
