-----------------------------------------------
I posted the comment in HBASE-7233.
Pasting the comment on this JIRA as this one is active
bq.Tags are a little different than our current fields because there are
multiple per Cell
The above comment is from Matt.
So basically we say we will have multiple tags for a Cell.
Which means cell which internally is now a represenation of a KV will have more
than one additional attributes added to it (which is Tags) and one among them
will be an ACL tag, visibility tag etc.
So now how will we say which tag to see if i want to know only the Visibility
part of the Cell?
I could see an tagIterator() api added that iterates thro the tags, so is it
like every time iterate to find out which is my Visisbility tag.
Will there be a mechanism which says visibility tag should be the first tag or
second .something like that?
