> Sometimes data in a table needs to be kept around but made inaccessible.
> Right now it is possible to offline a table or a partition, but not a
> specific column of a partition. Also, accessing an offlined table results in
> an error. With this change, it will be possible to mask a column at the
> partition level, causing all further queries to that column to return null.
