Google Cloud Spanner: Global consistency at scale
summary
Google Cloud Spanner appears as a fully managed, horizontally scalable relational DB with Live coding and demos showing Java client setup, schema DDL, inserts and reads. It uses Paxos and TrueTime atomic/GPS clocks to get a low millisecond epsilon for global strong consistency, runs regional instances as three-node replicas with 2 TB per node limits, exposes time‑bounded stale reads, counts mutations per cell (watch the 20,000 mutation limit per transaction), and claims CP behavior with four‑ to five‑nines SLAs.
