The text discusses GraphQL connections, a method for pagination in GraphQL APIs. The author explains how connections were designed at Facebook as part of their internal GraphQL server design and how they are used to paginate data in a way that avoids performance penalties. The author also provides an analogy comparing connections to graph theory, where edges represent the relationships between nodes. The text offers schema design recommendations for using connections in GraphQL APIs, including naming conventions for edge and connection types, and adding fields to edge types as metadata. The author emphasizes the importance of planning for future naming collisions and choosing detailed, descriptive names that can be deprecated in the future. Overall, the text aims to help developers understand the benefits and use cases of GraphQL connections, and provide guidance on how to implement them effectively in their own APIs.
