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 [...]
Understanding the maximum number of columns in a MySQL table
April 8, 2013 By 5 Comments
This post was initially going to be two sets of polls: “What is the maximum number of columns in MySQL?” and “What is the minimum maximum number of columns in MySQL?”. Before you read on, ponder those questions and come up with your own answers… and see if you’re right or can prove me wrong! [...]
Percona Welcomes MySQL 5.6!
February 25, 2013 By Leave a Comment
MySQL 5.6 was made generally available as a production-ready solution earlier this month. This release comes about 2 years after MySQL 5.5 was released, but MySQL 5.6 contains improvements started long before that – for example, work on the Innodb Full Text Search project was started over 6 years ago, in addition with many optimizer [...]
Percona and the MariaDB Foundation
December 19, 2012 By 3 Comments
There have been several reports (1,2,3) describing Percona’s stance regarding the MariaDB Foundation that are not totally accurate so I though it would be worth it to describe where we stand on this and related matters. First, let me say the creation of theMariaDB Foundation is a good thing for the MariaDB Community and I’m [...]

Thanks to all of our sponsors, speakers, speaker selection committee, event staff, and especially the attendees for making last week’s conference a resounding success.

If you don’t remember that announcement, here’s the short version: this is a tool to help you generate my.cnf files based on your server’s hardware and other characteristics.

linux.conf.au 2012 roundup
January 24, 2012 By Leave a Comment
I spent last week at linux.conf.au in Ballarat, Victoria (that’s the Victoria in Australia, not wherever else there may be one) which is only a pleasant two hour drive from my home town of Melbourne (Australia, not Florida). I sent an email internally to our experts detailing bits of the conference that may interest them [...]
MySQL opening .frm even when table is in table definition cache
November 21, 2011 By 8 Comments
or… “the case of Stewart recognizing parameters to the read() system call in strace output”. Last week, a colleague asked a question: I have an instance of MySQL with 100 tables and the table_definition_cache set to 1000. My understanding of this is that MySQL won’t revert to opening the FRM files to read the table [...]
