Explore the intricacies of auto-scaling challenges in cloud databases through this 33-minute conference talk from the Cloud Native Computing Foundation (CNCF). Delve into the complexities of running cloud databases on Kubernetes, focusing on the limitations of StatefulSets in scaling scenarios. Learn about different scaling models, including Break-first and Make-first approaches, and understand their respective advantages and disadvantages. Examine the obstacles preventing Make-first scaling with traditional StatefulSets and discover open-source solutions like Advanced StatefulSets and OpenKruise. Gain insights from a case study on ClickHouse Cloud's hybrid, Multi-StatefulSet approach to Make-first scaling, providing practical knowledge for addressing auto-scaling challenges in cloud database environments.
