Implementing GraphQL Successfully in the Backend
summary
A team moved from running a JS GraphQL reference implementation inside a .NET process to using a native GraphQL library, and solved performance problems by applying DataLoader, batching database queries with SQL IN, preloading and caching — reducing a worst-case example from 600 queries to 6. They advocate schema-first design for validation, documentation, GraphiQL explorer and client code generation, and recommend using per-request loaders or controlled global caches plus schema limits to prevent deep recursion and accidental exposure of sensitive fields.
