How to tell what mode a Table operator is in
Hi,
When I'm looking at the Flink plan in the UI and at an operator, is there a
way to tell if an operator is in Retract mode vs Upsert mode? Ideally we
want as many of our operators in Upsert mode as possible since our data
sources are all uniquely keyed.
Thanks!

If a stateful operator has also a stateful operator in its input
sub-pipeline, then it may receive retract messages. Operator like group
agg, stream-stream join or rank are stateful.
We can not show if the operator are receiving retract messages in the UI.
But your request is reasonable.

Our sinks are uniquely keyed as well. A couple of our joins are not until
an aggregate is performed however.
