1. case class ConsumerProperties[K, V](params: Map[String, String], topic: String, groupId: String, keyDeserializer: Deserializer[K], valueDeserializer: Deserializer[V], pollTimeout: FiniteDuration = 500 millis, pollRetryDelay: FiniteDuration = 500 millis) extends Product with Serializable

   

2. class KafkaGraphStageSink[K, V] extends GraphStage[SinkShape[ProducerMessage[K, V]]] with LazyLogging

   

3. class KafkaGraphStageSource[K, V] extends GraphStage[SourceShape[ConsumerRecord[K, V]]] with LazyLogging

   

4. case class KeyValueProducerMessage[K, V](key: K, value: V) extends ProducerMessage[K, V] with Product with Serializable

   

5. sealed trait ProducerMessage[K, V] extends AnyRef

   

6. case class ProducerProperties[K, V](params: Map[String, AnyRef], topic: String, keySerializer: Serializer[K], valueSerializer: Serializer[V], partitionizer: (V) ⇒ Option[Int] = (_: V) => None) extends Product with Serializable

   

7. class PropertiesBuilder extends AnyRef

   

8. case class PublisherWithCommitSink[K, V](publisher: Publisher[ConsumerRecord[K, V]], publisherActor: ActorRef, kafkaOffsetCommitSink: KafkaSink[ConsumerRecord[K, V]]) extends Product with Serializable

   

9. class ReactiveKafka extends AnyRef

   

10. case class ReactiveKafkaConsumer[K, V](properties: ConsumerProperties[K, V], topicsAndPartitions: Set[TopicPartition], topicPartitionOffsetsMap: Map[TopicPartition, Long]) extends Product with Serializable

    

    ReactiveKafkaConsumer allows for instantiating KafkaConsumer instances with several combinations of topic, partition, and offset parameters, depending on the use case.

11. case class SourceWithCommitSink[K, V](source: Source[ConsumerRecord[K, V], NotUsed], offsetCommitSink: Sink[ConsumerRecord[K, V], NotUsed], underlyingConsumer: ReactiveKafkaConsumer[K, V]) extends Product with Serializable

    

12. case class ValueProducerMessage[V](value: V) extends ProducerMessage[Array[Byte], V] with Product with Serializable
