Keep flexible GraphQL queries from turning into expensive operations that slow down your entire backend.
GraphQL gives clients a lot of freedom, but that freedom means the server cannot assume every query will be small or cheap. Deeply nested queries, expensive resolvers, repeated database calls, and large result sets can all become performance problems.
Improving GraphQL performance usually involves a combination of good schema design, efficient resolvers, batching, caching, pagination, query limits, and database optimization. The goal is not simply to make one query faster but to prevent expensive queries from affecting the whole system.
