    Description

      Currently, we cannot reuse the sort keys in the previous stage builder as the partition values or the sort-by values for range window bounds. For this reason, we're rebuilding the partition-by and sort-by expressions in the window stage builder. We should come up with a solution to avoid repeated evaluation.
