Performance-optimized resolvers with caching
The Netflix Problem: When REST Isn't Enough
Netflix processes over 500 billion log events daily across their microservices. Their analytics teams need to query logs with complex filters: "Show me all payment errors from the last hour, grouped by region, with user demographics."
REST APIs force multiple roundtrips:
GET /api/logs?service=payment&level=error&duration=1h
GET /api/regions/{regionId}/stats
GET /api/users/{userId}/demographicsGraphQL solves this with a single query that fetches exactly what's needed, reducing network overhead by 60%.
