Review Comment:
That PR (https://github.com/apache/spark/pull/48210) should be backported as
well. Maybe that one can be done first, and this one
(https://github.com/apache/spark/pull/49071) will then be 1:1 with my previous
(https://github.com/apache/spark/pull/48144).
We need the SqlBuilder and the compileExpression for this to work.
