We have a requirement in our apigee platform to block the calls of a consumer if the calls are getting failed. We have our quota policy which protects the backend but it doesn't protect the apigee platform. If a consumer sends large number of failed calls to apigee, our memory space of analytics is getting full which ultimately brings downs the analytics components. We are trying create a circuit breaker which will block the consumer to send any calls to apigee for certain time if there's large number failed call from them. Is there anything we can do to implement this through load balancer or any other way?
