Subject [jira] [Commented] (HBASE-10775) Revisit the HBASE-4012 byte comprare optimization
Date Mon, 29 Feb 2016 12:00:22 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10775?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15171792#comment-15171792

Anoop Sam John commented on HBASE-10775:

"It is as though we should compare first 5 bytes with old method and if any over, then filp
to Unsafe."
Worth trying and experimenting.
