Subject [jira] [Created] (HBASE-8063) Filter HFiles based on first/last key
Date Mon, 11 Mar 2013 03:35:12 GMT
Liang Xie created HBASE-8063:
--------------------------------

             Summary: Filter HFiles based on first/last key
                 Key: HBASE-8063
                 URL: https://issues.apache.org/jira/browse/HBASE-8063
             Project: HBase
          Issue Type: Improvement
          Components: Scanners
    Affects Versions: 0.98.0
            Reporter: Liang Xie
            Assignee: Liang Xie


# 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:)
