    To understand better
    
    >  We could make flat schema an optional mode or implement it as a separate TableSource as well.
    and this one
    
    > This could be solved if we use a flat schema and encode the nesting as columnFamily$column
    
    Are you talking about using seperators for it? May be am not getting your concern here. Ya I agree that nested schema is better API but if we go with flat schema then maintaining the family to qualifier relation may not be easy. As you said a seperate TableSource where we define such things would be better.
    Regarding HBaseTableSchema I think that is better so that we could modify that class for better serialization and deserialization by adding more logic for different types of classes. Even when we go with flat schema I think this type of class would help us to maintain the logic of family to qualifier mapping?
