Impressions of FOSDEM 13

FOSDEM 13 is now over, I am on my way home and I would like to share some thoughts sparkled by the intense atmosphere that I have lived in these two days in Brussels.

I have to admit, I was tempted to skip FOSDEM this year: the last 3 weeks have been crazily busy and I travelled a lot, leaving my family alone for too long. But now I am glad I made the effort.
For once, I will leave the comments around the MySQL talks to others, I am sure there will be posts on the matter. In this post I want to cover some of the non-MySQL talks and discussions I have attended and heard. Of course the topics that have been discussed are still relevant for MySQL and for the future of the MySQL ecosystem.
First of all, the number of attendees was impressive. The organisers claim there were more than 5,000 open source enthusiasts, in my opinion the number was even higher. Every room was …

Developing Libdrizzle

This weekend I am supposed to be giving a talk at FOSDEM on Libdrizzle.  Unfortunately my kids and I all fell ill on Thursday (my wife appears to be immune) so I had to cancel my plans (infecting 5000 people didn't seem wise :)

Instead I am writing this blog post about Libdrizzle and my part in it which covers some of what I was going to talk about.

History of LibdrizzleLibdrizzle started out as a from-scratch C connector for Drizzle and MySQL originally created by Eric Day.  It was designed to be high performance and use common standards to make it easy to work on.  In the summer of 2010 it was merged into the main Drizzle tree where development has been focused.  There were several attempts to split it out again but until now none were truly successful.

For a few years Brian …

Libdrizzle 5.1.2 released and Libdrizzle at FOSDEM

Libdrizzle is getting better and better with every release, and to reflect this we have two announcements to make.

First of all, Libdrizzle 5.1.2 has been released.  This release has several major bug fixes and performance enhancements.  Changes are as follows:

  • Non-blocking Windows connections are now more stable
  • Improvements to Windows building
  • Unix Socket connections are now more stable
  • Memory allocation/freeing cleanups (for performance and ease of code)
  • Network packet buffer now much more flexible
  • Many performance improvements (the bundled drizzle_binlogs tool is now around 10x faster on my i7 laptop)
  • Several other minor bug fixes

API chages:

  • drizzle_query_str() has been removed, drizzle_query() with a 0 byte length parameter now does the same thing.

As always you can …

Managing MySQL with Percona Toolkit by Frédéric Descamps

Frédéric Descamps of Percona.

Percona Toolkit is Maatkit & Aspersa combined. Opensource and the tools are very useful for a DBA.

You need Perl, DBI, DBD::mysql, Term::ReadKey. Most tools are written in Perl, and whatever is in Bash is being re-written in Perl. There is also a tarball or RPM or DEB packages.

Know your environment. The hardware & OS are crucial for you to know. How much memory/CPU do you use? Do you use swap? Is this a physical/virtual machine? Do you have free space? What kind of RAID controller? Volumes? Disk? What about the network interfaces? What IO schedulers are used? Which filesystem is the data stored on? To answer all that, just use pt-summary.

Know your MySQL environment. Version? Build? How many databases? Where is the data …

Replication features of 2011 by Sergey Petrunia

Sergey Petrunia of the MariaDB project & Monty Program.

MySQL 5.5 GA at the end of 2010. MariaDB 5.3 RC towards the end of 2011 (beta in June 2011).

MySQL 5.5 is merged to Percona Server 5.5 which included semi-sync replication, slave fsync options, atuomatic relay log recovery, RBR slave type conversions (question if this is useful or not), individual log flushing (very useful, but not many using), replication heartbeat, SHOW RELAYLOG EVENTS. About 2/3rds of the audience use MySQL 5.5 in production, with only 2 people using semi-sync replication.

MariaDB 5.3 brings replication features brings group commit in the binary log, which is merged into Percona Server 5.5. Checksums for binlog events which is merged from MySQL 5.6. Sergey goes in-depth about the …

MySQL Creatively in a Sandbox by Giuseppe Maxia

Giuseppe Maxia of Continuent and long time creator of MySQL Sandbox.

Only works on Unix-like servers. Works with MySQL, Percona & MariaDB servers. MySQL server has the data directory, the port and the socket – you can’t share these.

To use it: make_sandbox foo.tar.gz. Then just do ./use.

$SANDBOX_HOME is ~/sandboxes. You can also create ~/opt/mysql/ and if you have MySQL 5.0.91 binary in that directory, you can just do “sb 5.1.91″.

Sandbox has features to start replication systems as well. You can have varying master/slave setups with varying versions as well (good idea to test from MySQL -> MariaDB master->slave for migration).

You can now also play with tungsten-sandbox, which is a great way to start playing with …
