Matthias J. Sax commented on KAFKA-9471:
----------------------------------------

Btw: we plan to rework some part of the API and also how IQ works internally 
via https://issues.apache.org/jira/browse/KAFKA-9445 (that is related to 
https://issues.apache.org/jira/browse/KAFKA-6144) – hence, all those efforts 
should be synchronized. \cc [~NaviBrar] [~vvcephei] [~vinothchandar]

> In StreamThreadStateStoreProvider we have:
> {code}
> if (streamThread.state() == StreamThread.State.DEAD) {
>     return Collections.emptyList();
> {code}
> If user cannot retry anymore, we should throw exception which is handled in 
> the else block.
