BigTable does not work with tables. It contains objects belonging to a certain class, that have values for attributes of a certain type. You can define as much db.Model subclasses as you like and you can modify then at will. If you add new attributes (Property-s) make sure you gives them default values to receives for when the objects already stored in the BigTable are fetched. And don't change the Property Type of an attribute at will without considering if existing objects will be able to decode to this new type. Have a look at the article about changing the model definition.
