Lars George commented on HBASE-6222:
------------------------------------
bq. If we add a ColumnVisibility-like expression into the KV, we'd have to
update Comparators to exclude this portion from inclusion in sort.
That is the whole point of my proposal up top, using the new type and attaching
the tag bag *after* the key, the default code path stays untouched.
Sure this needs some extra conditional statements, but is easy to test for. The
rest of the tests need no overhaul. All the other approaches strike me as
overkill - although they might be worthwhile in their own right. So the
question is, what weapon do we choose, so that we solve one problem and
hopefully get the most collateral benefit?
Converting KVs into an interface and subclassing them, as you say, seems as
well as a major overhaul of the code base. Do we really want this right now?
And what does it give us besides the basis for the problem at hand?

> Saw an interesting article:

> "The Senate Armed Services Committee version of the fiscal 2013 national
> defense authorization act (S. 3254) would require DoD agencies to foreswear
> the Accumulo NoSQL database after Sept. 30, 2013, unless the DoD CIO
> certifies that there exists either no viable commercial open source database
> with security features comparable to [Accumulo] (such as the HBase or
> Cassandra databases)..."
> Not sure what a 'commercial open source database' is, and I'm not sure whats
> going on in the article, but tra-la-la'ing, if we had per-KeyValue 'security'
> like Accumulo's, we might put ourselves in the running for federal
> contributions?
