             Summary: [performance] Save-a-seek; hint HFileReader when Scan is a "Get" Scan
                 Key: HBASE-15457
                 URL: https://issues.apache.org/jira/browse/HBASE-15457
             Project: HBase
          Issue Type: Bug
            Reporter: stack


Have the Scan hint the lower-level Reader when its a 'Get' Scan. Reader is currently doing
checks for EOF and when time to load next block on each next invocation. Seems easy enough
to return null/end-of-scan if a get-scan and the next block is a different row.

Prompted by @daniel pol questions/suggestions over on HBASE-15392; see towards the end.
