public class SamplingThrottler extends DelegateAsyncProcessor implements Traceable, IdAware
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.processorshutdown, shuttingdown, started, starting, stopped, stopping, suspended, suspending| Constructor and Description |

AsyncProcessorProcessor.process(org.apache.camel.Exchange), but the caller supports having the exchange asynchronously processed.
If there was a failure processing then the caused Exception would be set on the Exchange.process in interface AsyncProcessorprocess in class DelegateAsyncProcessorexchange - the message exchangecallback - the AsyncCallback will be invoked when the processing of the exchange is completed.
If the exchange is completed synchronously, then the callback is also invoked synchronously.
The callback should therefore be careful of starting recursive loop.Apache Camel
