GraphQL Batching
GraphQL Batching is a performance optimization technique in GraphQL that groups multiple queries or mutations into a single network request to reduce latency and server load. It works by sending an array of operations in one HTTP request, allowing the server to process them together and return a combined response. This is particularly useful in scenarios where multiple data fetches are needed, such as in mobile apps or complex web interfaces.
Developers should use GraphQL Batching when building applications that require fetching multiple pieces of data simultaneously, as it minimizes the number of round trips to the server, improving performance and user experience. It's especially beneficial in high-latency environments like mobile networks or when dealing with nested queries that would otherwise trigger multiple requests. This technique helps reduce overhead and is supported by tools like Apollo Client and Relay.
