> # 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:)
