A SamplingThrottler is a special kind of throttler. It also limits the number of exchanges sent to a downstream endpoint. It differs from a normal throttler in that it will not queue exchanges above the threshold for a given period. Instead these exchanges will be stopped, precluding them from being processed at all by downstream consumers.

This kind of throttling can be useful for taking a sample from an exchange stream, rough consolidation of noisy and bursty exchange traffic or where queuing of throttled exchanges is undesirable.
