Subject [jira] [Commented] (HBASE-17877) Replace/improve HBase's byte[] comparator
Date Mon, 10 Apr 2017 05:50:41 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17877?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15962462#comment-15962462
] 

Vikas Vishwakarma commented on HBASE-17877:
-------------------------------------------

Overall there is very good improvement with the hadoop comparator observed using JMH also.
There is only the case where the byte array size % 8 is not zero where hadoop comparator is
showing slower results. Will check if this can be further optimized by using the HBase handling
of the left over bytes after % 8

> [~vik.karma] did some extensive tests and found that Hadoop's version is faster - dramatically
faster in some cases.
> Patch forthcoming.
