>
> In method markSemiJoinForDPP (HIVE-17399), the nDVs comparison should not
> have equality as there is a chance that the values are same on both sides and
> the branch is still marked as good when it shouldn't be.
> Add a configurable factor to see how useful this is if nDVs on smaller side
> are only slightly less than that on TS side.
