Rewrite everything in Rust? What we learned from introducing Rust in Strawberry-GraphQL
summary
Strawberry moves parsing and validation into Rust via a new library Rasberry, using Apollo Rust for validation and a shared GraphQL AST as the interface. Parsing and validation speed improves up to 7× and small queries run ~4.5× faster in end-to-end benchmarks. Two integration patterns are compared: mirror types (fast to construct, 20% better on large ASTs) versus instantiating Python types (lower runtime access overhead). Async callback overhead and Python–Rust crossings limit gains so migration proceeds incrementally on CPU‑bound subsystems with continuous benchmarking.
