Yeah, thanks. I know about neo4j but have been reluctant to try it due to the Java roots.
I also thought to try MagLev for a while, but couldn't get my hands onto it. If possible, I would prefer not to diverge from SQL Db. So maybe I am just after a good way of denormalising data... Or maybe just optimise relational DB for reads, and process the "propagations" as the backgrond job (It's ok to have a delay of a. couple of minutes)...
