Subject [jira] [Created] (KAFKA-5858) consumer.poll() shouldn't throw exception due to deserialization error
Date Fri, 08 Sep 2017 00:12:00 GMT
Jun Rao created KAFKA-5858:
------------------------------

             Summary: consumer.poll() shouldn't throw exception due to deserialization error
                 Key: KAFKA-5858
                 URL: https://issues.apache.org/jira/browse/KAFKA-5858
             Project: Kafka
          Issue Type: Improvement
    Affects Versions: 0.11.0.0
            Reporter: Jun Rao


Currently, the new consumer will throw an exception in poll() if it hits a deserialization
error. The consumer then can't make progress from this point on. It will be better to throw
the deserialization exception only when the key/value of the ConsumerRecord is accessed, like
the old consumer does.
