The conference is a free add-on independent conference that happens to take place at the same time & location as the MySQL User Conference & Expo. It focusses on high-performance databases. I’ll be giving a short introduction to CouchDB at 19:05 (07:05pm).
April 24th – 26th: JSConf, Washington, DC
April 27th – May 1st: CouchDB University & CouchDB Factory, Palo Alto, CA
Just a slight correction — the Percona conference is not an add-on, it’s a completely independent event we created, and were then invited to bring into the same venue. This is just to keep the record straight :-) Thanks!
