> # hbase-5010 introduced a filter mechanism based on timerange hint
> # 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:)
