The principle has been figured out. After the CRD is created, the APIServer updates the cached log records after the change.

@kangzhiqin We are also seeing this also but still don't understand why... The CRDs haven't changed? Or at least not to my knowledge so confused why we see hundreds of log lines every 5 mins that strikes me as kube-apiserver doing lots of work with the OpenAPI Spec that it doesn't need too?

When the CRD informer is created, the full synchronization mechanism is set to be performed every 5 minutes. The log is the evidence of full synchronization. I want you to focus on line 175 here.
