Ever wondered if two seemingly different GraphQL queries actually return the same data? Or how to ensure that complex queries—packed with type conditions and directives like @skip/@include—still mean the same thing after a major refactor? In this talk, we’ll explore a novel static analysis technique that efficiently checks whether one query’s response is always a subset of another’s. By performing this subset test in both directions, we can reliably determine query equivalence—bringing new clarity to complex GraphQL operations.
