I know Spanner uses atomic clocks to get tight time bounds on transactions. Since CockroachDB doesn't use atomic clocks they have to use a slightly different approach: "While Spanner provides linearizability, CockroachDB’s external consistency guarantee is by default only serializability, though with some features that can help bridge the gap in practice." "A simple statement of the contrast between Spanner and CockroachDB would be: Spanner always waits on writes for a short interval, whereas CockroachDB sometimes waits on reads for a longer interval." https://www.cockroachlabs.com/blog/living-without-atomic-clocks/ https://www.cockroachlabs.com/blog/living-without-atomic-clo...
