> 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.
