> The current max QPS is configured as 1000, which is much higher than the [400|https://kubernetes.io/docs/reference/command-line-tools-reference/kube-apiserver/] max requests inflight that the API server supports. This mismatch could cause requests to be dropped/rejected by the API server when the load is high (e.g. when a surge occurs in the number of pods that need to be scheduled). We should make the YK default match the API server default.
