Brian Stack from Render explains why Kubernetes scaling can break along a dimension most teams ignore: namespaces.

At Render scale, hundreds of thousands of namespaces made common DaemonSet patterns expensive. Calico and Vector were list-watching namespace data across every node, multiplying memory usage and putting pressure on the API server during restarts and rollouts.

You will learn:

- Why namespaces can become a hidden scaling bottleneck
- How DaemonSets multiply memory and control-plane pressure
- How profiling, staging clusters, and upstream collaboration freed 7 TiB
- Why pushing from an 80% fix to a complete fix can make teams faster
