The Supergraph Kickoff post discusses scaling a federated GraphQL Router to handle high traffic spikes, such as during events like the Super Bowl. The article highlights the importance of identifying bottlenecks in a federated GraphQL API and provides an overview of how Cosmo Router achieves this by implementing a heuristics-based cache warm-up strategy. This strategy eliminates cold starts and ensures that the Router can serve traffic efficiently without downtime. The post also touches on alternative approaches to warming up caches, such as using persisted queries or trusted documents, but notes their limitations. Overall, the article provides valuable insights into optimizing the performance of a federated GraphQL Router and showcases Cosmo Router's capabilities in handling high-traffic scenarios.
