Grafast: A Declarative Solution To GraphQL's Execution Woes

on YouTube ↗25m

" summary

Grafast replaces depth-first per-field resolvers with declarative planning that builds a request-wide execution plan, then executes breadth-first to batch and deduplicate I/O. It provides synchronous plan-resolvers and built-in steps like load many/load one to express batched DB and API calls, drops SQL queries and DB CPU, and shows ~5x throughput with average latency under 100 ms in the presented benchmark while remaining compatible via a resolver-emulation layer.
