-----------------------------------------

Talked to a few people, and there was no objection to close this.

> Handle accidental deletion of sink-topics as exceptional failure

>                 Key: KAFKA-10356
>                 URL: https://issues.apache.org/jira/browse/KAFKA-10356
>             Project: Kafka
>          Issue Type: Improvement
>          Components: streams
>            Reporter: Guozhang Wang
>            Assignee: Bruno Cadonna
>            Priority: Major

> Today when sink topics are deleted, the producer's send callback would 
> eventually return the UnknownTopicOrPartition exception after configured 
> max.delivery.ms whose default is 2min if EOS is not enabled (otherwise its 
> Integer.MAX_VALUE). Then in Streams implementation the exception would be 
> handled by ProductionExceptionHandler which by default would treat it as 
> `FAIL` and would cause the thread to die. If it treat it is CONTINUE then it 
> would be silently ignored and the sent records are lost silently. 
> We should improve this situation in Streams by special-handling 
> {{UnknownTopicOrPartition}} exception and trigger a rebalance as well, and 
> then in leader we can also check if the sink topic metadata exists, just like 
> source topic, and then follow the same logic as in 
> https://issues.apache.org/jira/browse/KAFKA-10355.
