Design a GraphQL schema by defining types, queries, mutations, and subscriptions, then implement efficient resolvers using DataLoader to batch data fetching and prevent the N+1 problem.

Cursor-based pagination in a GraphQL API uses the Relay connection specification to traverse data sets via opaque cursors, ensuring stable results even when underlying data changes during pagination.

Prevent the N+1 query problem in GraphQL resolvers by integrating DataLoader, which batches and caches database requests per request cycle to optimize data fetching performance.

Yes, you can implement GraphQL subscriptions for real-time notifications and manage microservice architectures by utilizing schema federation to distribute query execution across multiple services.

Structure a GraphQL API for a social media platform by generating comprehensive schemas for user profiles, posts, and comments, while integrating Relay pagination and DataLoader for optimized scalability.

GraphQL federation integrates with server frameworks and schema tools to compose multiple microservice APIs into a single unified graph, enabling scalable query execution across distributed services.
