SpacetimeDB: a short technical review
Summary
SpacetimeDB is examined as a free-standing, in-memory database with a single global lock and WASM-based user code execution inside critical sections. The review critiques the benchmark claims, discusses the trade-offs of a non-disk-backed design, and emphasizes end-to-end performance and reliability considerations over flashy results. It also contexts potential use cases and the marketing framing around LLM-era persistence.
