Description
Normalizer can be used to merge the regions which become emtpy post TTL expiry.
But it's picking the presplit regions as well. We can skip picking presplit regions while preparing the merge plans by looking at the number of storefiles along with size. Presplit regions have zero storefiles where as the TTL expired regions have 1 storefile with zero size.
