I enjoyed Stewart Smith’s MySQL storage engine blog last week. In it he noted “I cannot emphasize how much more interesting TokuDB would be if it were open source.” Well, with our open source announcement yesterday, hopefully we are getting...

I had the chance to work on an interesting case last week, and I thought I’d share what I think is a little known goodie from Percona Toolkit for MySQL called pt-query-digest. One customer was suffering from periods of high load on their database server, leading...
