Via loudthinking.com, DHH points to the Magic Multi-Connections plugin by Nic Williams. This plugin could be used in any number of ways, Nic has a recipe for randomly selecting a connection from a pool, but the plugin could just as easily be made to work with a set of model objects spread across multiple databases.
The interesting story behind this is on DHH’s blog. Read: Alex Payne’s interview, then read David’s response, and finally the post from Sunday Scaling to multiple databases with Rails.

Kevin makes some important points about how the community should/does respond to people pointing out things that RoR doesn’t do well. He also has a good analysis of the response Alex Payne’s interview and offers some ideas for how this conversation could have happened differently.


Today on "Rails of our Lives"...
What I'm wondering is: why isn't something like this (multi-connections) part of the core Rails distribution? In my opinion there are far too many plugins out there that should have been part of Rails.
Most of the loudthinking.com links appear to be dead now. Got new links?
