Defusing the Kubernetes API Performance Minefield - Madhav Jivrajani, UIUC & Marek Siarkowicz, Google
Thursday April 3, 2025 16:00 - 16:30 BST
Level 1 | Hall Entrance S10 | Room A
Kubernetes enables a wide landscape of CNCF projects and organisations to build upon its foundation and extend its functionality through custom controllers. But anyone who has deployed an operator at scale, quickly discovers that the Kubernetes API is a performance minefield. Forget to set resourceVersion when listing pods? Your control plane explodes! This talk delves into recent enhancements in Kubernetes designed to defuse this performance minefield. We'll explore the improved storage layer that allows caching more types of requests, effectively halving request latency and reducing the load on etcd. Don't let your cluster fall victim to faulty controllers – join us to learn how these changes mitigate risks, boost performance, and contribute to a more stable and reliable Kubernetes experience. We'll explore how the storage layer improves API responsiveness and predictability, and you'll understand the impact of these changes on scalability, reliability, and overall user experience.
