> For processors that are stateless and support batching, it should be safe to get and process multiple input FlowFiles for each onTrigger() call.  
> This should amortize the cost of session.get(), session.checkpoint(), session.commit() as well as any setup in onTrigger() that isn't dependent on the FlowFile(s) attributes or content.
> An AbstractBatchingProcessor type should reduce boilerplate code in candidate processors and encourage uniform configurability via a property to control batch size.
