> Key: HBASE-9679
> URL: https://issues.apache.org/jira/browse/HBASE-9679
> Project: HBase
> Issue Type: Improvement
> Components: HFile
> Affects Versions: 0.95.2, 0.94.12
> 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:)
