The GraphQL Caching Death Spiral

GraphQL elegantly solves under-fetching for mobile connections by aggregating requests. However, it violently breaks standard HTTP GET caching mechanisms. Since every request is a massive POST to a single endpoint, intermediate CDNs and reverse proxies cannot cache it natively.

For read-heavy workloads (like e-commerce catalogs), standard REST edges will always outperform unoptimized GraphQL.
