> Repeat calls to {{PartitionIterator.hasNext}} where both calls return {{false}} can result in timeouts. For example, {{{}KafkaBatchPartitionReader.next(){}}}, which calls {{consumer.get}} (which can potentially timeout with repeat calls), is called by {{{}PartitionIterator.hasNext{}}}. Thus, repeat calls to {{PartitionIterator.hasNext}} by its parent could timeout.
