Richard Yu updated KAFKA-8431:
------------------------------
Labels: needs-kip (was: )
> Add a onTimeoutExpired callback to Kafka Consumer
> -------------------------------------------------
>
> Key: KAFKA-8431
> URL: https://issues.apache.org/jira/browse/KAFKA-8431
> Project: Kafka
> Issue Type: Improvement
> Components: consumer
> Reporter: Richard Yu
> Priority: Minor
> Labels: needs-kip
>
> Currently, after the changes introduced in KIP-266, many methods in Kafka
> Consumer have a bounded execution time given by a user specified {{Duration}}
> parameter. However, in some cases, some methods could not perform their
> operations in the allocated timeout. In this case, the user might wish to
> have a {{onTimeoutExpired}} callback which would be called should a blocking
> method timeout before any results could be returned.
> The user can implement something like described above, but Kafka can spare
> the user the necessity of coding such a feature if we can support one by
> itself.
> One possible use of this callback is to retry the method (e.g. the
> {{onTimeoutExpired}} callback triggers another call to the same method after
> some allocated time).
