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.

Usually people do this around New Year, I will do it in February. Actually, I was inspired to do this after reviewing all the talks for this year's MySQL Conference - what a snapshot into the state of where we are! It made me realize we've made important progress in the past year, worth taking a moment to celebrate it. So here we go...

Diversification

In the past few years there was a lot of fear and doubt about MySQL due to Oracle taking over the ownership. But if you ask me, I was more worried for MySQL because of MySQL itself. I've often said that if MySQL had been a healthy open source project - like the other 3 components in the LAMP stack - then most of the NoSQL technologies we've seen come about would never have been started as their own projects, because it would have been more natural to build those needs on top of MySQL. You could have had a key-value store (HandlerSocket, Memcache API...), sharding (Spider) and clustering (Galera). You could have had a graph storage engine (OQGraph engine isn't quite it, I understand it is internally an InnoDB table still?). There could even have been MapReduce functionality, although I do think the Hadoop ecosystem targets problems that actually are better solved without MySQL.

The program for this year's MySQL conference is now published.

As regular readers will remember, I served on the program committee this year and was one of those who appealed for people to send in great proposals. I would now like to thank all of you that sent in proposals. On my quick count we had over 250 proposals, and if I look at my own ratings I'd say about 180 of them were really good, conference worthy talks (and this already excludes some pretty good talks). A related piece of trivia was that this might have been the first year ever that the deadline for the Call for Proposals wasn't extended, which possibly took some of you by surprise. We simply got so many good talks by the deadline, that there wasn't any need to.

Just wanted to say I'm so happy: http://www.mysqlperformanceblog.com/2012/01/09/announcement-of-percona-x...

And also that this is a significant moment in the evolution of MySQL - things will never be the same again.

MySQL::Sandbox 3.0.24 was released yesterday, with many new features.

More than vanilla MySQL

If you have missed my previous announcement, here's the gist of it. MySQL Sandbox can now deal with tarballs from either Percona Server or MariaDB. The main difference after this change is that you can now create a directory called <PREFIX>5.5.16 and make_sandbox will recognize it as well as the plain 5.5.16.

$ make_sandbox --export_binaries --add_prefix=ps \
   Percona-Server-5.5.11-rel20.2-114.Darwin.i386.tar.gz  \
   -- --sandbox_directory=msb_ps5_5_11
unpacking Percona-Server-5.5.11-rel20.2-114.Darwin.i386.tar.gz
[…]
installing with the following parameters:
upper_directory                = /Users/gmax/sandboxes
sandbox_directory              = msb_ps5_5_11
[…]
basedir                        = $HOME/opt/mysql/ps5.5.11
tmpdir                         = 
[…]
Your sandbox server was installed in $HOME/sandboxes/msb_ps5_5_11

After the binary export, subsequent installations will be easier:

$ make_sandbox ps5.5.11

The same commands can be used for MariaDB. At the moment, make_sandbox does not recognize other packages, but adding them should not be a big deal, provided that such packages look like MySQL. It wouldn't work with Drizzle, because it lacks the main ingredients for MySQL installation.

High Performance sandboxes

While testing parallel replication and prefetch slaves with Tungsten Replicator, I realized that I was doing too much manual fiddling with my scripts. Since I need more performant servers, I added the basic items that I need to modify to enable a faster server. Now, using the '--high_performance' option with make_sandbox, you get a server that is much better than out-of-the-box MySQL. To avoid problems with too much RAM, I am using a default of 512 MB for InnoDB, which is not enough for really demanding tests, but at least it is a good placeholder in the sandbox configuration file, should you need to modify it.

$ make_sandbox 5.1.60 -- --high_performance
[…]
innodb-flush-method=O_DIRECT ; \
innodb-log-file-size=50M ; \
innodb_buffer_pool_size=512M ; \
max_allowed_packet=48M ; \
max-connections=350 ; \
innodb-additional-mem-pool-size=50M ; \
innodb-log-buffer-size=50M ; sync_binlog=0 ; \
innodb-thread-concurrency=0 ; log-error=msandbox.err
[…]

Standalone masters and slaves

MySQL Sandbox has had the ability of creating replicated systems for years. Yet, sometimes you need a stand-alone master server that you want to use for some odd experiment. Similarly, you may want to create a slave of a specific master without having a full replication system. One case where you would like this ability is when you want to try replicating between servers of different versions.

$ make_sandbox 5.1.57 -- --master
[…]
my_clause                      = server-id=5157 ; log-bin=mysql-bin ; log-error=msandbox.err
[…]
Your sandbox server was installed in $HOME/sandboxes/msb_5_1_57

$ make_sandbox 5.5.10 -- --slaveof='master_port=5157' 
[…]
my_clause                      = server-id=5510 ; log-bin=mysql-bin ; log-error=msandbox.err
[…]
Your sandbox server was installed in $HOME/sandboxes/msb_5_5_10

A year ago I posted a blog on The state of MySQL forks: co-operating without co-operating. (Also Giuseppe wrote about the topic at that time, and Peter Zaitsev covers it in his conference keynotes.) So I've been wondering if it would be good to write an update on the topic now, and in that case what to write.

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 proposal as if your job depended on it!
Please read an update on Percona Live MySQL Conference & Expo 2012.

Speakers in Europe have some more duty, though. This is also the time to submit talks for FOSDEM MySQL DevRoom. Thanks to Frédéric Descamps and Sergey Petrunia, we have Room H.1309 with 150 seats on Sunday 5th February 2012, all day. The deadline to submit a talk proposal is December 26th. There is no review committee. Like we did on past editions, as soon as the talks are submitted, we will ask everyone to vote on the talks via Twitter or email. More updates will come soon. Of course, participation to FOSDEM DevRoom is not limited to European speakers. There have been several brave speakers who have willingly crossed the pond to offer their services at European conferences before, and they are welcome to repeat the experience. Submit your talk proposals now.
