Update: Apparently Spanner is way slower than I thought in "slow" datacenters, doing a round trip for every transactional read. So this would absolutely stomp that. (Although spanner, as a higher level system, has the ability to move different data to be fast in different regions built in, which is nice, and as I said it will probably have to be a layer feature in the fdb world)
