> In the case of the consumer.poll timing out, the KafkaRecordReader could
> return with no values in the records iterator which then causes the
> KafkaRecordReader to exit prematurely[1]. To fix this we need to probably
> better track the start/end offset and that progress vs the null value.
> Additionally if we wanted to be smarter we could do some "backoff" for the
> timeout or just have consumer specify a larger value.
