final case classMessage[K, V, +PassThrough](record: ProducerRecord[K, V], passThrough: PassThrough) extends Product with Serializable
Input element of Producer#commitableSink and Producer#flow.
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 Consumer#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.
