Class DefaultErrorHandler

All Implemented Interfaces:
CommonErrorHandler, DeliveryAttemptAware

public class DefaultErrorHandler extends FailedBatchProcessor implements CommonErrorHandler
An error handler that, for record listeners, seeks to the current offset for each topic in the remaining records. Used to rewind partitions after a message failure so that it can be replayed. For batch listeners, seeks to the current offset for each topic in a batch of records. Used to rewind partitions after a message failure so that the batch can be replayed. If the listener throws a BatchListenerFailedException, with the failed record. The records before the record will have their offsets committed and the partitions for the remaining records will be repositioned and/or the failed record can be recovered and skipped. If some other exception is thrown, or a valid record is not provided in the exception, error handling is delegated to a FallbackBatchErrorHandler with this handler's BackOff. If the record is recovered, its offset is committed. This is a replacement for the legacy SeekToCurrentErrorHandler and SeekToCurrentBatchErrorHandler (but the fallback now can send the messages to a recoverer after retries are completed instead of retrying indefinitely).

  • Constructor Details

    • DefaultErrorHandler

      public DefaultErrorHandler()
      Construct an instance with the default recoverer which simply logs the record after 10 (maxFailures) have occurred for a topic/partition/offset, with the default back off (9 retries, no delay).
    • DefaultErrorHandler

      public DefaultErrorHandler(BackOff backOff)
      Construct an instance with the default recoverer which simply logs the record after the backOff returns STOP for a topic/partition/offset.
      Parameters:
      backOff - the BackOff.
    • DefaultErrorHandler

      public DefaultErrorHandler(ConsumerRecordRecoverer recoverer)
      Construct an instance with the provided recoverer which will be called after 10 (maxFailures) have occurred for a topic/partition/offset.
      Parameters:
      recoverer - the recoverer.
    • DefaultErrorHandler

      public DefaultErrorHandler(@Nullable ConsumerRecordRecoverer recoverer, BackOff backOff)
      Construct an instance with the provided recoverer which will be called after the backOff returns STOP for a topic/partition/offset.
      Parameters:
      recoverer - the recoverer; if null, the default (logging) recoverer is used.
      backOff - the BackOff.
  • Method Details

    • setCommitRecovered

      public void setCommitRecovered(boolean commitRecovered)
      Set to true to commit the offset for a recovered record. The container must be configured with ContainerProperties.AckMode.MANUAL_IMMEDIATE. Whether or not the commit is sync or async depends on the container's syncCommits property.
      Overrides:
      setCommitRecovered in class FailedRecordProcessor
      Parameters:
      commitRecovered - true to commit.
    • isAckAfterHandle

      public boolean isAckAfterHandle()
      Description copied from interface: CommonErrorHandler
      Return true if the offset should be committed for a handled error (no exception thrown).
      Specified by:
      isAckAfterHandle in interface CommonErrorHandler
      Returns:
      true to commit.
    • setAckAfterHandle

      public void setAckAfterHandle(boolean ackAfterHandle)
      Description copied from interface: CommonErrorHandler
      Set to false to prevent the container from committing the offset of a recovered record (when the error handler does not itself throw an exception).
      Specified by:
      setAckAfterHandle in interface CommonErrorHandler
      Parameters:
      ackAfterHandle - false to not commit.
    • remainingRecords

      public boolean remainingRecords()
      Description copied from interface: CommonErrorHandler
      Return false if this error handler should only receive the current failed record; remaining records will be passed to the listener after the error handler returns. When true (default), all remaining records including the failed record are passed to the error handler.
      Specified by:
      remainingRecords in interface CommonErrorHandler
      Returns:
      false to receive only the failed record.
      See Also:
    • deliveryAttemptHeader

      public boolean deliveryAttemptHeader()
      Description copied from interface: CommonErrorHandler
      Return true if this error handler supports delivery attempts headers.
      Specified by:
      deliveryAttemptHeader in interface CommonErrorHandler
      Returns:
      true if capable.
    • handleRemaining

      public void handleRemaining(Exception thrownException, List<org.apache.kafka.clients.consumer.ConsumerRecord<?,?>> records, org.apache.kafka.clients.consumer.Consumer<?,?> consumer, MessageListenerContainer container)
      Description copied from interface: CommonErrorHandler
      Handle the exception for a record listener when CommonErrorHandler.remainingRecords() returns true. The failed record and all the remaining records from the poll are passed in. Usually used when the error handler performs seeks so that the remaining records will be redelivered on the next poll.
      Specified by:
      handleRemaining in interface CommonErrorHandler
      Parameters:
      thrownException - the exception.
      records - the remaining records including the one that failed.
      consumer - the consumer.
      container - the container.
      See Also:
    • handleBatch

      public void handleBatch(Exception thrownException, org.apache.kafka.clients.consumer.ConsumerRecords<?,?> data, org.apache.kafka.clients.consumer.Consumer<?,?> consumer, MessageListenerContainer container, Runnable invokeListener)
      Description copied from interface: CommonErrorHandler
      Handle the exception for a batch listener. The complete ConsumerRecords from the poll is supplied. The error handler needs to perform seeks if you wish to reprocess the records in the batch.
      Specified by:
      handleBatch in interface CommonErrorHandler
      Parameters:
      thrownException - the exception.
      data - the consumer records.
      consumer - the consumer.
      container - the container.
      invokeListener - a callback to re-invoke the listener.
    • handleOtherException

      public void handleOtherException(Exception thrownException, org.apache.kafka.clients.consumer.Consumer<?,?> consumer, MessageListenerContainer container, boolean batchListener)
      Description copied from interface: CommonErrorHandler
      Called when an exception is thrown with no records available, e.g. if the consumer poll throws an exception.
      Specified by:
      handleOtherException in interface CommonErrorHandler
      Parameters:
      thrownException - the exception.
      consumer - the consumer.
      container - the container.
      batchListener - true if the listener is a batch listener.
