PassThroughMessage

final case class PassThroughMessage[K, V, +PassThrough](passThrough: PassThrough) extends Envelope[K, V, PassThrough] with Product with Serializable

Envelope implementation that does not produce anything to Kafka, flows emit a PassThroughResult for every element processed.

The passThrough field may hold any element that is passed through the Producer.flow and included in the Results. That is useful when some context is needed to be passed on downstream operations. That could be done with unzip/zip, but this is more convenient. It can for example be a ConsumerMessage.CommittableOffset or ConsumerMessage.CommittableOffsetBatch that can be committed later in the flow.
