Caching is one of the most powerful tools for improving API performance—but in a federated GraphQL architecture, stale data can quickly become a serious challenge. In this session, we will dive into how event-driven patterns can enable precise cache invalidation at the subgraph level, keeping your data fresh without sacrificing speed. You will learn key design principles, practical integration strategies for GraphQL subgraphs, and the business impact of a smarter caching approach. We will also explore real-world use cases and demonstrate how CloudEvents can standardize event-based workflows across your architecture. Whether you are optimizing an existing caching layer or just beginning your caching journey, this talk will equip you with practical strategies to reduce latency, lower infrastructure costs, and deliver more reliable experiences to your users.
