There was a problem hiding this comment.
Should assert if length is specified or try to honor it (e.g.: allow it if it's less than the length of the list).

This ensures that dim table here produces only positive values in the
valuecolumn, so that the filter included in the join does not result in a degenerative join. There is an existingtest_dpp_empty_relationwhich should be testing the scenario that involves DPP+AQE with empty relations from degenerative joins.
