Subject [jira] [Commented] (HBASE-7897) Add support for tags to Cell Interface
Date Thu, 14 Mar 2013 20:54:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7897?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13602711#comment-13602711
] 

Andrew Purtell commented on HBASE-7897:
---------------------------------------

bq. Would we need a tag dictionary/registry of some sort to ensure that different co-processors
(or whatever) don't try to use the same tags?

That would be analogous to rewriting the KV data, i.e. different coprocessors writing to the
same value coordiate. I think we should handle both the same way: use at your own risk.

> 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.
