----------------------------------------------

             Summary: Read path optimizations after HBASE-11425 profiling
                 Key: HBASE-14188
                 URL: https://issues.apache.org/jira/browse/HBASE-14188
             Project: HBase
          Issue Type: Sub-task
            Reporter: ramkrishna.s.vasudevan
            Assignee: ramkrishna.s.vasudevan


This subtask deals with some improvments that can be done in the read path (scans) after the
changes for HBASE-11425 went in.
-> Avoid CellUtil.setSequenceId in hot path.
-> Use BBUtils in the MultibyteBuff.
-> Use ByteBuff.skip() API in HFileReader rather than MultiByteBuff.position().
