ConsumerMessage

Type Members

trait Committable extends AnyRef

Commit an offset that is included in a CommittableMessage.
Commit an offset that is included in a CommittableMessage. If you need to store offsets in anything other than Kafka, this API should not be used.
This interface might move into akka.stream
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.
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.
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.
final case class GroupTopicPartition(groupId: String, topic: String, partition: Int) extends Product with Serializable

groupId, topic, partition key for an offset position.
final case class PartitionOffset(key: GroupTopicPartition, offset: Long) extends Product with Serializable

Offset position for a groupId, topic, partition.
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
