  December 17, 2012

  This post comes as response to 5 Tips for migrating your MySQL server to a Galera Cluster by Henrik Ingo (Galera), which is a good read. This post is a bit lengthy which is one of the reasons why I didn't just comment on said post. The Galera talk in London was indeed well crowded, [...]

• My take on privatized MySQL security bugs

  November 8, 2012

  A couple weeks ago I submitted Bug #67315: Crashing server by stored function referencing user defined variable in query. If you press that link, you can't see the bug (though I can as I submitted it). This is due to Oracle's policy for security-related bugs. Tomas Ulin, Vice President MySQL Development at Oracle , was kind [...]

  MySQL 5.6 offers the groundbreaking online DDL operations for InnoDB. Most common use cases will enjoy this feature, and the need for online alter table scripts will decrease. This is a killer feature! I've put this new feature to the usability test. How did it go? Not too well, I'm afraid. [Updates to this text [...]

• Thoughts on MySQL 5.6 new replication features

  October 15, 2012

  After playing a little bit with MySQL 5.6 (RC), and following closely on Giuseppe's MySQL 5.6 replication gotchas (and bugs), I was having some thoughts.

• MySQL 5.6 new features: the user's perspective

  October 5, 2012

  This is a yet-another compilation of the new MySQL 5.6 feature set. It is not a complete drill down. This list reflects what I believe to be the interesting new features user and usability -wise.

Here's a brief list, and apologies if I've missed anyone: Monty Program Announcing MariaDB 5.3. (and later Announcing MariaDB 5.5.23 GA) Tokutek Announcing TokuDB [...]

• Thoughts on using MySQL plugins

  April 3, 2012

  I'm giving thoughts on the viability of MySQL plugins. This is due to a particular experience I've had, which is thankfully solved. However, it left some bitter taste in my mouth. MySQL plugins are a tricky business. To create a plugin, you must compile it against the MySQL version you wish the users to use [...]
