Description

1. hbase-5010 introduced a filter mechanism based on timerange hint
2. this jira is a placeholder just for keyrange hint: currently, low layer(hfile reader) has first/last key getter methods already. we should utilize this information to pre-filte hfiles while choosing scanners from storefiles.

It's just a raw thought right now, no patch available yet. I'll summit a patch asap if it's reasonable, welcome to give some suggestions/comments
