    Publish records to Kafka topics and then continue the flow.

    Publish records to Kafka topics and then continue the flow. The flow can only be used with a Transactional.source that emits a ConsumerMessage.TransactionalMessage. The flow requires a unique transactional.id across all app instances. The flow will override producer properties to enable Kafka exactly-once transactional support.

    API MAY CHANGE

    Publish records to Kafka topics and then continue the flow. The flow can only be used with a Transactional.sourceWithOffsetContext that carries ConsumerMessage.PartitionOffset as context. The flow requires a unique transactional.id across all app instances. The flow will override producer properties to enable Kafka exactly-once transactional support.

    This flow is intended to be used with Akka's [flow with context](https://doc.akka.io/docs/akka/current/stream/operators/Flow/asFlowWithContext.html) and Transactional.sourceWithOffsetContext.

    Sink that is aware of the ConsumerMessage.TransactionalMessage.partitionOffset from a Transactional.source. It will initialize, begin, produce, and commit the consumer offset as part of a transaction.

    Transactional source to setup a stream for Exactly Only Once (EoS) kafka message semantics.

    Transactional source to setup a stream for Exactly Only Once (EoS) kafka message semantics. To enable EoS it's necessary to use the Transactional.sink or Transactional.flow (for passthrough).
