--------------------------------
[~vvcephei]
thank you so much for your input on this. Understood everything well expect the
last point, related to the emit-on-change. I do not see why
ktable0.join(ktable1.groupby.reduce)
Can cause idempotent updates ?
I red the KIP KIP-557 and the example with the PageViewID, SessionID, and can
see the idempotent update here, but not with the code above. Would you please
elaborate a bit on this ?
