> There is an ongoing discussion on how to handle the default case (no duplicates/deletes) and how to use the new CompactingMemstore in such a case.
> One improvement is to avoid the StoreScanner and go with a simple MemstoreScanner. This avoids lot of comparisons that the StoreScanner does. Just raising this sub-task as part of some analysis going on.
