graphql

Graphene brings GraphQL to Django. I define types mapping to models and create resolvers for queries and mutations. Clients request exactly the data they need, reducing over-fetching. I use DjangoObjectType for automatic schema generation from models.

GraphQL endpoints can be abused with huge queries that are expensive to parse and execute. Persisted queries let clients send a hash (e.g. sha256:...) instead of the full query, and the server only executes queries it recognizes. This reduces payload

GraphQL makes it very easy to accidentally create N+1 query explosions. DataLoader batches requests for the same resource during a single tick and gives you per-request caching. The trick is scoping: loaders must be per-request, not global singletons,
