> During the compaction time, HBase will generate a store scanner which will
> scan a list of store files. And it would be more efficient to filer out the
> expired store file since there is no need to read any key values from these
> store files.
> This optimization has been already implemented on 89-fb and this is the
> building block for HBASE-5199 as well. It is supposed to be no-ops to compact
> the expired store files.
