Ok, but Does It Scale?

Spacetime scales across three independent dimensions—compute, storage, and networking—by offering high-performance handling of contended OLTP transactions and tools for parallelizable workloads, unlike traditional single-node databases that lack horizontal scaling. It contrasts with systems such as CockroachDB, Spanner, and Aurora DSQL, highlighting their engineering strengths while noting the overheads those platforms incur when scaling horizontally.
