Subject [jira] [Commented] (HBASE-12345) Unsafe based Comparator for BB
Date Sun, 26 Oct 2014 09:03:35 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14184437#comment-14184437
] 

Anoop Sam John commented on HBASE-12345:
----------------------------------------

We can expose APIs getLong/Int etc in BBUtil which uses Unsafe, if it is available, and use
that to read from BB. We will need that in HFileReaderV2/V3 seek, next etc.  Also when the
Cell is backed by buffer and the lengths , like rklength, tagsLength etc are part of the buffer,
we can make use of the API for faster reads.
