Sink
Overview and Key Concepts
The sink is used to destroy flow items that are finished in the model. Once a flow item has traveled into a sink, it cannot be recovered. Any data collection involving flow items that are about to leave the model should be done either before the flow item enters the sink or in the sink's OnEntry trigger.
The sink is a fixed resource. Since it destroys all flow items it receives, the sink does not have any output logic.
