public class AcknowledgerConsumerWorker<T extends Acknowledgeable> extends Object implements MeasuredConsumerWorker<T,AcknowledgerMetrics>
A ProcessorWorker that receives inputs from upstream, acknowledges the input, and then discards the input.

On source failure, the worker will fail the task.

On acknowledgement failure, the worker may fail the task, at the discretion of its failure handler.

On interrupt, the worker will stop receiving messages immediately.

In all cases, the worker will wait for all outstanding acks to finish before stopping or failing the task.
