Neat! How do you handle cross-geo latency? I know google has to rely on precise clocks to make this work in spanner

Its split into geographically located shards so you don't need to sync across the global keyspace which is very different from the Spanner model. You have a configurable amount of durability so you can set how much latency you want to tolerate vs how much geo-durability you want to have. If you want to have full planet durability you are going to hit a pretty bit latency penalty
