Getting a self-hosted geospatial API to cold start in 1.3s on a single core
Wrote up the engineering work behind running pygeoapi on ephemeral Fly.io microVMs for Waystones Cloud. Single CPU core, scale-to-zero.
Five issues we hit: a POSIX file truncation race on the OpenAPI endpoint, a self-deadlocking warmup script, why we generate the OpenAPI document in TypeScript rather than Python, CPU scheduling conflicts with nice -n 19, and a frontend timing gap.
