@FunctionalInterface public interface BatchAcknowledgingConsumerAwareMessageListener<K,V> extends BatchMessageListener<K,V>
Listener for handling a batch of incoming Kafka messages, propagating an acknowledgment handle that recipients can invoke when the message has been processed. The list is created from the consumer records object returned by a poll. Access to theConsumer
is provided.- Since:
