Term	Kind	Topic	What it is
GraphQL N+1 Problem DataLoader Pattern	concept	GraphQL	The query explosion that occurs when each item in a list independently resolves its nested fields, turning one request into hundreds of database calls.
N+1 Resolution DataLoader Problem	concept	GraphQL	The default GraphQL execution behaviour in which each field resolver runs per item, producing one query per row instead of one query per request.
Persisted Query	pattern	GraphQL	Registering allowed queries in advance and having clients send an identifier instead of the query text.
Query Cost Analysis Query Complexity Limiting, Cost-Based Rate Limiting	practice	GraphQL	Computing the resource cost of a client-specified query before executing it, so that an API which lets clients define their own requests cannot be asked to do unbounded work.
