Anoop Sam John commented on HBASE-18749:
----------------------------------------
The issue is not using CF specific TR from Scan.
On the code, will it be better that the Segments know which Store/CF it belongs
to. Than we pass Store instance every time into shouldSeek() method. Per cf
we have one MS and that will have N Segments. In Compacting Memstore, already
the Store ref is there.
> Apply the TimeRange from ColumnFamily to filter the segment scanner
