Why can CRD conversion webhooks become a bottleneck?

Senior Kubernetes
Quick Answer CRD conversion webhooks translate CRD objects between API versions (v1alpha1 รขโ€ โ€™ v1beta1 รขโ€ โ€™ v1). Every read or write of a CRD object in a different version triggers a webhook call. In clusters with many CRD instances or high API throughput, these synchronous webhook calls add latency to every API operation. Keep webhook response times under 10ms.

Answer

Conversion runs on every read/write across versions, overwhelming webhook servers.
