Hi All!

Excuse my stupid question, I am pretty new to the Table/SQL API and I am
trying to play around with it implementing and running a few use-cases.

I have a simple window join + aggregation, grouped on some id that I want
to write to Kafka but I am hitting the following error:

"AppendStreamTableSink requires that Table has only insert changes."

If I understand correctly the problem here is that since updates are
possible within a single group, we have a retract stream and the Kafka Sink
cannot handle that. I tried to search for the solution but I haven't found
any satisfying answers.

How can I simply tell the INSERT logic to ignore previous values and just
always keep sending the latest (like you would see it on the CLI output).

Thank you!
Gyula
