Lars Hofhansl commented on PHOENIX-172:
---------------------------------------

The sort order of RVC has to be consistent with the PKs natural sort order. It 
specifically does *not* translate comparing each column.
(a,b) < (x,y) is true exactly when the pk (a,b) sorts before pk (x,y).

In your example above (b,1) > (b, 2) based on the key's sort order. That's how 
RVC should behave. And it's what they do in fact, right?

> Support the ability for a client to do query more

> Clients often need the ability to "page" through query results that have more 
> row results than are displayable on a single screen. SQL provides LIMIT and 
> OFFSET which is often used for this purpose, however supporting OFFSET in a 
> performant manner is not possible with HBase. Instead, an alternate way of 
> supporting query-more functionality (suggested by @larsh) is through  [row 
> values 
> constructors](http://publib.boulder.ibm.com/infocenter/soliddb/v6r3/index.jsp?topic=/com.ibm.swg.im.soliddb.sql.doc/doc/row.value.constructors.html)
>   which has been in the SQL spec since SQL-92. It has PostGres support as 
> well with the benefits explained well
