- Maybe implement DB::BulkDeleteForRange(start_key, end_key)
|
|
that would blow away files whose ranges are entirely contained
|
|
within [start_key..end_key]? For Chrome, deletion of obsolete
|
|
object stores, etc. can be done in the background anyway, so
|
|
probably not that important.
|
|
- There have been requests for MultiGet.
|
|
|
|
After a range is completely deleted, what gets rid of the
|
|
corresponding files if we do no future changes to that range. Make
|
|
the conditions for triggering compactions fire in more situations?
