Hi, The following post discusses how FriendFeed uses MySQL in a schema-less data model: http://bret.appspot.com/entry/how-friendfeed-uses-mysql. They report an improvement both on speed, stability and flexibility. I find this very interesting, and actually quite troubling. Does one really benefit from moving *away* from RDBMS's? My natural way of thinking is totally different - whenever we can define the business logic in relational terms, we should let the database do the heavylifting, and push *more* logic onto it - cause that's what they do best. I marked this as off topic, cause it's not really Drupal related, but I'm curious about your insights about this approach. We've had our bunch of off-topics in this and the consulting list for this week, so my apologies if this is too much. Cheers, -- Yuval Hager [@] yuval@avramzon.net
