The other day a discussion in #mysql on freenode developed concering possible issues arising from using auto increment on primary key fields due to the danger of hotspots. Since I am currently preparing a new talk first to be held at php|works on SQL performance tuning I thought that the topic would make for a perfect warming up post on the general topic.

Well when ever people talk about integrating LiveUser into their project they usually at some point ask: "where is the documentation?" Or worse they say "I wasted hours to get this stuff working, it looks promising but I gave up".

Yes, this is it! This is my first real personal homepage. Ironic that I have been developing PHP, once called personal homepage, for over 5 years now and never really had a personal homepage of my own. However previously the websites I created where mostly for customers. Some web pages were created together with friends of co-workers.
