Sergey Shelukhin commented on HBASE-7902:
-----------------------------------------
bq. but in this case the compaction does have in principle all the information,
and produce a correct state at the time it runs.
Not counting memstore... so if we similarly don't count a couple storefiles we
are just extending the time window, not changing the behavior :)
Although I agree practically this should stay.

> Deletes are only removed during major compaction now. However, in presence of
> file ordering, deletes can be removed during minor compaction too, as long as
