GCP Spanner Distributed

Cloud Spanner is a globally distributed relational database. Replicate across regions (US, EU, APAC), write in one region, read from nearest replica. ACID transactions across the globe—Spanner uses GPS clocks and atomic clocks to maintain strong consistency without sacrificing availability. Think: take Postgres (relational, transactions), scale it globally (Bigtable-style distribution), that's Spanner.
