  1. ss
  2. - Stats
  3. db
  4. - Maybe implement DB::BulkDeleteForRange(start_key, end_key)
  5. that would blow away files whose ranges are entirely contained
  6. within [start_key..end_key]? For Chrome, deletion of obsolete
  7. object stores, etc. can be done in the background anyway, so
  8. probably not that important.
  9. After a range is completely deleted, what gets rid of the
  10. corresponding files if we do no future changes to that range. Make
  11. the conditions for triggering compactions fire in more situations?
