GraphQL Federation

GraphQL Federation is a method for combining multiple GraphQL APIs into a single, unified schema. Imagine each service or team managing its own part of data—federation allows these separate pieces to work together seamlessly, so clients can query across all of them with a single request. It promotes modularity, making complex systems easier to develop and maintain, while still providing a unified interface. Essentially, federation enables different data sources to collaborate efficiently, giving developers a flexible and scalable way to build comprehensive APIs.
