Major Description
In Atlas-0.5, the name field had the format, dbname.tablename@clustername. But along the way, on trunk, it was changed to clustername.dbname.tablename to make it intuitive. But just before atlas-0.6 release, to make it backward compatible(as some users were already using atlas in prod), it had to be changed it back to dbname.tablename@clustername.
