I’ve reposted the slides from my Spockproxy talk (Spockproxy is a Sharding only version of the MySQL proxy). Since I’ve have to move this web site it’s been some effort to move all of the files into their new homes.
These slides are in a variety of formats and have loads of great information if you’re considering a sharding solution – even if that is not Spockproxy. Of course once you see how easy it is you’ll put it on your short list.
The slides are available at http://www.frankf.us/projects/spockproxy/ If you want to hear the talk you’ll have to invite me.
