mathias kluba commented on PHOENIX-1311:
----------------------------------------
The advantage of mapping to CATALOG is that users with permissions on his
namespace will be able to create/alter tables that requires modification in the
SYSTEM.CATALOG table.
With multiple namespaces, one can have multiple catalogs like
"CATALOG_01.SYSTEM.CATALOG".
It's especially useful with dynamic columns...

> Hbase (HBASE-8015) has the concept of namespaces in the form of
> myNamespace:MyTable it would be great if Phoenix leveraged this feature to
> give a database like feature on top of the table.
> Maybe to stay close to Hbase it could also be a create DB:Table...
> or DB.Table which is a more standard annotation?
