    Description

      To determine if a column descriptor is unused, we call listStorageDescriptorsWithCD(), which may return a big list of SDs. This can severely slow down dropping partitions.

      We can add a maximum number of SDs to return, and just ask for 1 SD, since we are just doing an existential check.
