Jamie Brandon commented on KAFKA-12594:
---------------------------------------
Actually I see 998218 records in the 'accepted_transactions' topic, but that is
a different issue...
> Self-join produces no ouput, and prevents other streams from producing output

> I have a simple kafka-streams example which just reads in some transactions
> and writes them back out again.

> This works fine and I see the right output in 'accepted_transactions'.
> If I uncomment the left join at line 58, then not only do I not get any
> output for the left join, but I don't get any output in
> 'accepted_transactions' either.
