Subject [jira] [Created] (KAFKA-9274) Gracefully handle timeout exceptions on Kafka Streams
Date Thu, 05 Dec 2019 21:02:00 GMT
Boyang Chen created KAFKA-9274:

             Summary: Gracefully handle timeout exceptions on Kafka Streams
                 Key: KAFKA-9274
                 URL: https://issues.apache.org/jira/browse/KAFKA-9274
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: Boyang Chen

Right now streams don't treat timeout exception as retriable in general by throwing it to
the application level. If not handled by the user, this would kill the stream thread unfortunately.

In fact, timeouts happen mostly due to network issue or server side unavailability. Hard failure
on client seems to be an over-kill.

We would like to discuss what's the best practice to handle timeout exceptions on Streams.
The current state is still brainstorming and consolidate all the cases that contain timeout
exception within this ticket.
