----------------------------------
Hi [~mcorgan], thanks for your comments, i haven't looked into HBASE-4676 yet,
will try to do a simple benchmark if possible after maked an raw patch.
IIRC, these two manners are not conflict, at least in leveldb, both
prefix-compaction and above "faked" index key are exist:)
> optimize hfile index size like leveldb's
> ByteWiseComparatorImpl::FindShortestSeparator() style
> ----------------------------------------------------------------------------------------------
