April 11, 2013 By 6 Comments
In preparing for this month’s Percona Live MySQL Conference and Expo, I’ve been reminiscing about the annual MySQL User Conference’s history – the 9 times it previously took place in its various reincarnations – and there are a lot of good things, fun things to remember. 2003 was the year that marked the first MySQL user conference [...]
What I’m looking forward to at Percona Live (MySQL Users Conference)
April 4, 2013 By 1 Comment
This is my 10th year attending and speaking at the MySQL Users Conference (as the Percona Live MySQL Conference and Expo was originally called back in 2003), and for me it does not get tiring.

As is typical at the beginning of every April, many of us who submitted talks to the Percona Live MySQL Conference and Expo are wondering why we submitted so many.

Implications of Metadata Locking Changes in MySQL 5.5
February 1, 2013 By 9 Comments
While most of the talk recently has mostly been around the new changes in MySQL 5.6 (and that is understandable), I have had lately some very interesting cases to deal with, with respect to the Metadata Locking related changes that were introduced in MySQL 5.5.3. It appears that the implications of Metadata Locking have not [...]
