> It is possible for {{KeyValueStore.put(K key, V value)}} to throw an 
> exception unrelated to the store in question. Due to [the way that 
> {{RecordCollector.send}} is currently 
> implemented|https://github.com/confluentinc/kafka/blob/3.2.x/streams/src/main/java/org/apache/kafka/streams/processor/internals/RecordCollectorImpl.java#L76]
> the exception thrown would be for any previous record produced by the stream 
> task, possibly for a completely unrelated topic the same task is producing to.
> This can be very confusing for someone attempting to correctly handle 
> exceptions thrown by put(), as they would not be able to add any additional 
> debugging information to understand the operation that caused the problem. 
> Worse, such logging would likely confuse the user, since they might mislead 
> themselves into thinking the changelog record created by calling put() caused 
> the problem.
> Given that there is likely no way for the user to recover from an exception 
> thrown by an unrelated produce request, it is questionable whether we should 
> even try to raise the exception at this level. A short-term fix would be to 
> simply delegate this exception to the uncaught exception handler.
