Sanity GROQ CDN cache behavior under concurrent identical requests and rate-limit limits
Sanity serves read queries through an edge CDN at api.cdn.sanity.io, which caches GROQ results according to a configurable staleness window. Public documentation describes the staleness parameter and Cache-Control headers, but does not state whether the CDN coalesces or deduplicates concurrent identical cache misses before contacting the Content Lake origin.
