case class Transaction[Value](value: Value, partOffset: PartitionOffset) extends Tracked[Value] with HasPartition[Value] with Product with Serializable
A Tracked wrapper type using the Transactional Kafka interface. Transactional commits
ensure the topic offset updates and message production happen atomicly.
This is necessary for exactly-once message semantics.
- Value
The type of the object contained by the tracking wrapper.
- value
The wrapped object.
- partOffset
Transaction information.
