[openstack-dev] [Nova] Does Nova really need an SQL database?

There were some concerns expressed at the summit about scheduler 
scalability in Nova, and a little recollection of Boris' proposal to keep 
the needed state in memory.  I also heard one guy say that he thinks Nova 
does not really need a general SQL database, that a NOSQL database with a 
bit of denormalization and/or client-maintained secondary indices could 
suffice.  Has that sort of thing been considered before?  What is the 
community's level of interest in exploring that?
