Matthias J. Sax commented on KAFKA-5861:
----------------------------------------
Thanks for reporting this. What do you exactly mean by "more consuming threads"
-- more than one? More than input partitions? What does "many messages" mean
here? It implies that for low data rate, your application works fine? When does
it break down?
> KStream close( withTimeout ) - does not work under load conditions in the
> multi-threaded KStream application

> Key: KAFKA-5861
> URL: https://issues.apache.org/jira/browse/KAFKA-5861
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 0.11.0.0
> Reporter: Seweryn Habdank-Wojewodzki
>
> Recently implemented close( withTimeout ) for streams does not work under
> load conditions in the multi-threaded KStream application.
> Where there are more consuming threads and there many messages in stream,
> then close ( withTimeout ) does not work.
> 1. Timeout is not respected at all and
> 2. application is hanging in some streaming chaos. Theoretically threads are
> working - they are busy with themselves, so the app cannot end, but they are
> not processing any further messages.
