Hi, @fhueske.
I will update PR with fixed version soon.
But I have a question. Is deduplication at In#toRexNode really needed since
we are going to use hashset anyway? It's easy to implement, we just can take
distinct values here.
And I think I will open PR with subquery implementation today. It's rather
straightforward, but works.
