Thus, a rate limiting rule can define the universe of requests to which it is applied, and can then separately define the way in which those requests will be grouped. For example, a rule could define a rate limit for all requests from clients in a certain realm, but group those requests by appId. A separate different rule could apply to the same realm, but group all the request from that realm together into a single bucket.
