API Priority and Fairness controls the behavior of the Kubernetes API server in an overload situation. You can find more information about it in the API Priority and Fairness documentation. Diagnostics Every HTTP response from an API server with the priority and fairness feature enabled has two extra headers: X-Kubernetes-PF-FlowSchema-UID and X-Kubernetes-PF-PriorityLevel-UID, noting the flow schema that matched the request and the priority level to which it was assigned, respectively.
