August 12, 2007 By 4 Comments
Yesterday I ran into the article which sheds some light on FaceBook search implementation. As we’re recently a lot into search having implemented a bunch of search projects ourselves and helped number a of customers with their full text search needs I decided to post my thoughts on this matter. First I was surprised article [...]

About a week ago Marten send me email pointing to his article published on Jays Blog (Come on Marten, it is time for you to get your own blog). I should have replied much earlier but only found time to do that now. So here is my list 1. Be Pluggable Unlike many OpenSource projects [...]
Can Innodb Read-Ahead reduce read performance ?
June 26, 2007 By 2 Comments
I ran into pretty interesting behavior today. We needed to dump and reload large database and we had pretty good IO subsystem so we started number of mysqldump processes in parallel.

I’ve run into the following thread couple of days ago: Basically someone is using sphinx to perform search simply on attributes (date, group etc) and get sorted result set and claiming it is way faster than getting it with MySQL.

Life Beyond MySQL
