Thanks Alfred... To use both ndb or Expando class, first I have to create a class which extends ndb or Expando... But I am getting entity name at run time, So I do not have any fixed entity.
Our users can store their own entities at run time. Suppose I am creating one class with "*CustomEntity**"* which extends expando, and I am giving custom entity name in *"Key Name",* then all the entities will be stored in table "*CustomEntity"*. But is there any way store each entity in separate tables with table name as entity name ??
