Elliott Clark commented on HBASE-7902:
--------------------------------------
Unless I'm missing something I'm not sure that holds if the timestamps are put
out of order.
Hfile 1:
Put(ts = 2)
Hfile 2:
Put(ts = 4)
Delete(ts = 2)
Delete(ts = 1)
Hfile 3:
Put(ts = 1)
If you now compact File 1 and File 2 and remove the delete then put in file 3
will be visible.
> deletes may be removed during minor compaction, depending on file set

> 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
> there's no file that is not being compacted that is older than the files that
> are.
