Matt Corgan commented on HBASE-7897:
------------------------------------
{quote}I'd say no. What you thinking?{quote}I'd say no too. I shouldn't have
talked about it so much =). Perhaps the content of the tags can be inferred
from a column family setting rather than a per-cell attribute.
Thinking on it a little more, I'm trying to convey that the Cell is a very
low-level interface whose purpose is only to delineate a group of byte[]'s at a
moment in time. It is up to the levels above Cell to interpret what is in the
byte[]'s. A comparison would be a multi-part row key with int-String-int. The
Cell only knows that we have a row key byte[], and the levels on top are free
to use those bytes any way they like. We don't want to expose an Iterator on
the rowKey section of the Cell...
There is another discussion about the use cases for tags and how those tags
should be written into the byte[], but this particular jira is only focused on
what to add to the Cell interface. It's an important discussion no doubt, but
I wonder if it matters here?

> 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 discussion here:
