stack commented on HBASE-6222:
------------------------------

[~gqchen] A put that broadened visibility would be for the current put only?  
How would it effect already-put values?  (I can see how an Increment would have 
to check current visibility setting to see if it was allowed increment it -- 
ditto for check and put)  The DeleteFamily, DeleteColumn case is interesting.  
HBase would have to change how it does these operation pretty radically -- at 
least the way we do delete family.  [~larsgeorge] Anything to report?  It has 
to be per KV?  Or could it be metacolumn/Oracle Label Security-like?

> 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?
