Databases

Storing and querying data with real guarantees: transactions, replication, and consistency held across many machines — how a distributed SQL database keeps its promises at scale.

Explainers

• How Google Spanner Works — A database that spans the planet and still behaves as if every transaction ran one at a time. The trick is TrueTime — a clock that answers with a range instead of an instant, so the database can wait out its own uncertainty. We walk how the data is split and copied, the waiting rule that keeps ordering honest, and when you do not need any of it — drawn, computed, and animated.
