org.springframework.kafka.listener.KafkaExceptionLogLevelAware

org.springframework.kafka.listener.ExceptionClassifier

org.springframework.kafka.listener.FailedRecordProcessor

org.springframework.kafka.listener.FailedBatchProcessor

All Implemented Interfaces:

DeliveryAttemptAware

Direct Known Subclasses:

DefaultErrorHandler, RecoveringBatchErrorHandler

public abstract class FailedBatchProcessor
extends FailedRecordProcessor

Subclass of FailedRecordProcessor that can process (and recover) a batch. If the listener throws a BatchListenerFailedException, the offsets prior to the failed record are committed and the remaining records have seeks performed. When the retries are exhausted, the failed record is sent to the recoverer instead of being included in the seeks. If other exceptions are thrown processing is delegated to the fallback handler.
