[jira] [Created] (HBASE-9679) Binary search in HFile block

Liang Xie created HBASE-9679:
--------------------------------

             Summary: Binary search in HFile block
                 Key: HBASE-9679
                 URL: https://issues.apache.org/jira/browse/HBASE-9679
             Project: HBase
          Issue Type: Improvement
          Components: HFile
    Affects Versions: 0.94.12, 0.95.2
            Reporter: Liang Xie
            Assignee: Liang Xie
            Priority: Minor


It's not a top priority issue, seems to me.
Right now hbase do a linear scan to search a key within a hfile block on interst, in special case, e.g. 100% read scenario or high read/write ratio scanario, it's useful to do a binary search improvement to reduce the CPU cost and response time,  i think the biggest benefit should be the cpu:)
