 * `nginx.ingress.kubernetes.io/limit-rps`: number of requests accepted from a given IP each second. The burst limit is set to this limit multiplied by the burst multiplier, the default multiplier is 5. When clients exceed this limit,  [limit-req-status-code](https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/configmap/#limit-req-status-code) ***default:*** 503 is returned.
 * `nginx.ingress.kubernetes.io/limit-rpm`: number of requests accepted from a given IP each minute. The burst limit is set to this limit multiplied by the burst multiplier, the default multiplier is 5. When clients exceed this limit,  [limit-req-status-code](https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/configmap/#limit-req-status-code) ***default:*** 503 is returned.
 * `nginx.ingress.kubernetes.io/limit-burst-multiplier`: multiplier of the limit rate for burst size. The default burst multiplier is 5, this annotation override the default multiplier. When clients exceed this limit,  [limit-req-status-code](https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/configmap/#limit-req-status-code) ***default:*** 503 is returned.
+* `nginx.ingress.kubernetes.io/limit-no-burst`: When set to true, burst size is not set. The default value is false.
+* `nginx.ingress.kubernetes.io/limit-delay`: The delay parameter defines the point at which, within the burst size, excessive requests are throttled (delayed) to comply with the defined rate limit. When set to non negative number, it means nodelay. Default value is -1.
 * `nginx.ingress.kubernetes.io/limit-rate-after`: initial number of kilobytes after which the further transmission of a response to a given connection will be rate limited. This feature must be used with [proxy-buffering](#proxy-buffering) enabled.
 * `nginx.ingress.kubernetes.io/limit-rate`: number of kilobytes per second allowed to send to a given connection.  The zero value disables rate limiting. This feature must be used with [proxy-buffering](#proxy-buffering) enabled.
 * `nginx.ingress.kubernetes.io/limit-whitelist`: client IP source ranges to be excluded from rate-limiting. The value is a comma separated list of CIDRs.
+* `nginx.ingress.kubernetes.io/limit-shared-size`: Set size of shared memory zone. The default value is 5.

 If you specify multiple annotations in a single Ingress rule, limits are applied in the order `limit-connections`, `limit-rpm`, `limit-rps`.
