    Description

      Add bloomfiltering to hfile. Can be enabled on a family-level basis. Ability to configure a row vs row+col level bloom. We size the bloomfilter with the number of entries we are about to flush which seems like usually we'd be making a filter too big, so our implementation needs to take that into account.
