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

Envelope implementation that produces a single message to a Kafka topic, flows emit a Result for every element processed.

The record contains a topic name to which the record is being sent, an optional partition number, and an optional key and value.

The passThrough field may hold any element that is passed through the Producer.flow and included in the Result. 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.
