Subject [jira] [Commented] (HBASE-8496) Implement tags and the internals of how a tag should look like
Date Sat, 08 Jun 2013 19:16:22 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8496?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13678821#comment-13678821

Andrew Purtell commented on HBASE-8496:

bq. Is putting tags after value a good idea?

Oops, So you mean that tags needs to be part of the KV comparisions itself. Was thinking that
would be a major change. So we need to sort KVs based on tags also?

I would strongly caution against this. Tags will be _arbitrary_ metadata and won't have anything
to do with locating the value itself. 

On the other hand, some use cases may want it, see https://issues.apache.org/jira/browse/HBASE-6222?focusedCommentId=13396190&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13396190

I don't have a good answer for resolving this conflict. 

We may just want to live with the constraints imposed by not having tags be part of the key.
This would significantly simplify implementation.
