> As far as I know, every database that scales beyond a single node (for performance) is eventually consistent That's SO not true. Spanner, Amazon's S3 are some of the biggest databases on the planet, and they are strongly consistent. > Otherwise you've gotta wait for a sync between nodes before a response can be given, which would effectively force your cluster to have worse performance then running on single node again. Yes, you are trading latency for fault-tolerance, but so what? What if the resulting latency is still more than good enough? There is no shortage of real large-scale applications where this is the case.
