How the Fission Algorithm Works: Top-Down GraphQL Federation Design

Fission is a stateful schema graph engine that revolutionizes the traditional GraphQL Federation workflow by enabling a top-down approach to API design. Unlike the conventional method where subgraphs are composed into a supergraph, Fission allows architects to first design the supergraph, which it then decomposes into subgraph specifications, managing entity keys, directives, and validations automatically. This process simplifies schema changes and enhances collaboration by synchronizing supergraph and subgraph views, allowing seamless propagation of changes and ensuring consistent validation. Fission automates complex operations like cascading renames and transitive dependency propagation, reducing the need for manual intervention while still requiring architects to make key design decisions. Integrated with WunderGraph Hub, Fission provides a collaborative platform for teams to design, evolve, and implement APIs efficiently, facilitating a monolithic design approach with microservices implementation.
