In my opinion, one of the most profound ideas in Spanner is the introduction of TrueTime API and the guarantee provided in the implementation. I wonder if this project is going to have something similar?
From the description, it sounds like they're not at the moment. Instead, they seem to be aiming for the globally replicated, consistent, SQL-supporting features. Nothing wrong with that -- the world could use more geographically-aware database implementations. Seems like they'd be able to make use of the time sync for more efficient replication/failover/transactions in the future when the hardware is more widely available.
