> ... including the ability to run the SQL engine on top of any key/value store ... Note that you can do that today with the virtual tables interface in SQLite 3. For example several people have written virtual tables where the underlying data is in a csv file, I wrote one that backends into CouchDB etc. It is a little ugly in that SQLite semantics bleed through the interface (eg BestIndex method) but does work. http://www.sqlite.org/vtab.html http://www.sqlite.org/vtab.html
