Advantages of BooleanProperty in GAE NDB

Question

Does using property type BooleanProperty give us any performance advantage(like faster query response or anything else) compared to using another property type. The property is used as a flag(only two possible values)

I use GAE with Python

Example 1:

class H(ndb.Model): 
    p = ndb.BooleanProperty() 

Example 2:

class H(ndb.Model): 
    p = ndb.IntegerProperty() # with possible values as 0 or 1 

Is example 1 approach better in terms of performance or storage

I know, by convention, it is appropriate to use example 1 approach but i am curious to know if we get any benefits

Answer 1

A Boolean takes less space than an Integer.

You have to have millions of records, however, to notice any difference.
