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 [...]

Open Development vs Making a Big Splash
May 21, 2009 By 28 Comments
I find it very interesting how Sun does not get the very basic principle of true community Open Source development – you’ve got to give up on making a big splash.

November 26, 2008 By 8 Comments
I have written before – MyISAM Does Not Scale, or it does quite well – two main things stopping you is table locks and global mutex on the KeyCache. Table Locks are not the issue for Read Only workload and write intensive workloads can be dealt with by using with many tables but Key Cache [...]

Today I was working with the client loading data to MyISAM tables at very high rate. Hundreds of millions rows are loaded daily into single MySQL instance with bursts up to 100K of records/sec which need to be inserted (in the table with few indexes). It was good not all records had to go to [...]
Will Percona Support Drizzle ?
August 6, 2008 By 10 Comments

Choosing innodb_buffer_pool_size
November 3, 2007 By 39 Comments
My last post about Innodb Performance Optimization got a lot of comments choosing proper innodb_buffer_pool_size and indeed I oversimplified things a bit too much, so let me write a bit better description. Innodb Buffer Pool is by far the most important option for Innodb Performance and it must be set correctly. I’ve seen a lot [...]

October 24, 2007 By 12 Comments
OK, I am not getting too much people feedback on what would they like to hear about on MySQL Users Conference, so I went ahead and submitted few presentation ideas.
