> I discovered from review discussion -
> [https://github.com/apache/spark/pull/31630#discussion_r581774000] , that we
> can eliminate LEFT ANTI join (with no join condition) to empty relation, if
> the right side is known to be non-empty. So with AQE, this is doable similar
> to [https://github.com/apache/spark/pull/29484] .
