Reporter: Jamie Brandon
I have a simple kafka-streams example which just reads in some transactions and
writes them back out again.
https://github.com/jamii/streaming-consistency/blob/c1f504e73141405ee6cd0c7f217604d643babf81/kafka-streams/src/main/java/Demo.java
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.
