If you specify multiple annotations in a single Ingress rule, `limit-rpm`, and then `limit-rps` takes precedence.
+The annotation `ingress.kubernetes.io/limit-rate`, `ingress.kubernetes.io/limit-rate-after` define a limit the rate of response transmission to a client. The rate is specified in bytes per second. The zero value disables rate limiting. The limit is set per a request, and so if a client simultaneously opens two connections, the overall rate will be twice as much as the specified limit.
+
+`ingress.kubernetes.io/limit-rate-after`: sets the initial amount after which the further transmission of a response to a client will be rate limited.
+
+`ingress.kubernetes.io/limit-rate`: rate of request that accepted from a client each second.
+
+To configure this setting globally for all Ingress rules, the `limit-rate-after` and `limit-rate` value may be set in the NGINX ConfigMap. if you set the value in ingress annotation will cover global setting.
