@fhueske , this is the PR with the code generated distinct aggregation for
OVER. You mentioned that the value of the aggregation should be a Row, but what
is kept in the distinct state is just the event value, not its "aggregation
value state". Perhaps you can try to explain it better to me so that I can
complete this PR and we can move on. What do you think?
