Type Members

1.  trait Committable extends AnyRef

   Carries offsets from Kafka for aggregation and committing by the scaladsl.Committer or javadsl.Committer.

   Carries offsets from Kafka for aggregation and committing by the scaladsl.Committer or javadsl.Committer.

   Committable may be a single offset in CommittableOffset or CommittableOffsetMetadata, or a number of offsets aggregated as CommittableOffsetBatch.

2.  final case class CommittableMessage[K, V](record: ConsumerRecord[K, V], committableOffset: CommittableOffset) extends Product with Serializable

   Output element of committableSource.

   Output element of committableSource. The offset can be committed via the included CommittableOffset.

3.  sealed trait CommittableOffset extends Committable

   Included in CommittableMessage.

   Included in CommittableMessage. Makes it possible to commit an offset with the Committable#commitScaladsl / Committable#commitJavadsl method or aggregate several offsets in a batch before committing.

   Note that the offset position that is committed to Kafka will automatically be one more than the offset of the message, because the committed offset should be the next message your application will consume, i.e. lastProcessedMessageOffset + 1.

4.  trait CommittableOffsetBatch extends Committable

   For improved efficiency it is good to aggregate several CommittableOffset, using this class, before committing them.

   For improved efficiency it is good to aggregate several CommittableOffset, using this class, before committing them. Start with the empty batch.

6.  final case class GroupTopicPartition(groupId: String, topic: String, partition: Int) extends Product with Serializable

   groupId, topic, partition key for an offset position.

7.  sealed class PartitionOffset extends Product2[GroupTopicPartition, Long] with Serializable

   Offset position for a groupId, topic, partition.

8.  final case class PartitionOffsetMetadata(key: GroupTopicPartition, offset: Long, metadata: String) extends Product with Serializable

   Offset position and metadata for a groupId, topic, partition.

9.  final case class TransactionalMessage[K, V](record: ConsumerRecord[K, V], partitionOffset: PartitionOffset) extends Product with Serializable

   Output element of transactionalSource.

   Output element of transactionalSource. The offset is automatically committed as by the Producer
