As described here : hashicorp/consul#4810 blocking queries on missing services do not block when there is a lot of changes happening on a DC. While we want to keep
minDelayBetweenRequests
relatively small, we would like to limit the rate of queries on missing services as they won't ever block (until the service is registered).In cache, when an empty response is received, wait at least minDelayOnEmptyResult before running the next request. If minDelayBetweenRequest is greater than minDelayOnEmptyResult, wait minDelayOnEmptyResult instead.
