Hello
I'm looking for a way in sdk to get access to predicates inside udx (transform or custom source) to reduce workload inside function (to implement something like partition elimination). I see there is a planContext, but it seems it does not know anything about outer query. Is there any way to make row reduction possible inside udx?
