Subject [jira] [Commented] (HBASE-6222) Add per-KeyValue Security
Date Mon, 18 Jun 2012 19:50:44 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6222?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13396190#comment-13396190
] 

Keith Turner commented on HBASE-6222:
-------------------------------------

The security label in the Accumulo key is called Column Visibility.  Its part of the sort
order and uniqueness of an 
Accumulo key.  The key is sorted on row, then column fam, column qual, then column vis, then
timestamp, then delete flag.  So for example the following entries would be distinct and sort
in the following way.

row=1234 cf=name cq=last cv=S&GOLF ts=5 val=Smith
row=1234 cf=name cq=last cv=S&GOLF ts=4 val=Smit
row=1234 cf=name cq=last cv=U ts=9 val=Doe

> Saw an interesting article: http://www.fiercegovernmentit.com/story/sasc-accumulo-language-pro-open-source-say-proponents/2012-06-14
> "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?
