I think learning the low-level API is a must for all Java developers. It opens your mind to possible solutions that don't exist. With JDO/JPA/Objectify/db.Model, every Entity has the same schema because that makes it easier to map data to object definitions. With the low-level API, you can have dynamically named properties, partial indexes (Objectify supports this), and you understand the distinction between empty and null properties.
