Spanner to CockroachDB Mapping

Google’s Spanner (2012 paper) introduced globally distributed, strongly consistent relational databases using TrueTime (atomic clocks + GPS). CockroachDB and YugabyteDB are open-source systems inspired by Spanner’s design, using hybrid logical clocks instead of TrueTime. Cloud Spanner exposes the internal system on GCP.
