> Add TimeoutException to KafkaConsumer#position()
> ------------------------------------------------
>
> Key: KAFKA-6608
> URL: https://issues.apache.org/jira/browse/KAFKA-6608
> Project: Kafka
> Issue Type: Improvement
> Components: consumer
> Reporter: Richard Yu
> Assignee: Richard Yu
> Priority: Blocker
> Labels: kip
>
> In KAFKA-4879, Kafka Consumer hangs indefinitely due to Fetcher's {{timeout}} being set to {{Long.MAX_VALUE}}. While fixing this issue, it was pointed out that if a timeout was added to methods which commits offsets synchronously, a stricter control on time could be achieved.
