Subject [jira] [Commented] (HBASE-13448) New Cell implementation with cached component offsets/lengths
Date Wed, 06 May 2015 05:30:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14529956#comment-14529956
] 

Anoop Sam John commented on HBASE-13448:
----------------------------------------

So we can better cache these
rowLength -  Short - 2 bytes
keyLength - int       - 4 bytes
valueLength - int    - 4 bytes

Total 10 bytes per cell..  The key length parsing is used by multiple items like getFamilyOffset/Length
etc.
