Subject [jira] [Commented] (HBASE-7897) Add support for tags to Cell Interface
Date Tue, 07 May 2013 02:41:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7897?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13650405#comment-13650405

ramkrishna.s.vasudevan commented on HBASE-7897:
-----------------------------------------------

bq.Maybe change getTagsArray() to be plural like the other two?
Ok will do that.
bq.If we did want to have a getNumTags(), we'd probably want to store numTags as a VInt somewhere
in the cell.
This is what i have done currently in my implementation.  Not as a Vint but a single byte.
So i thought having getNumTags() would be meaningful.  If we don't have this then we should
every time use some way to find out the number of tags given the tagByteArray.
But as you said just to know if a Cell has tags or not getTagsLength() > 0 should help.

> Cell Interface has suppport for mvcc.   The only thing we'd add to Cell in the near future
is support for tags it would seem.  Should be easy to add.  Should add it now.  See backing

> Would be good to get these in now.
> Marking as 0.96.  Can more later.
