Do i load my entity faster using key in objectify?

Question

i can load using key

Employee e = ofy().load().key(Key.create( Employee.class,employeeId)).now();

But if i find it using some field

Employee e = ofy().load().type(Employee.class).filter("employeeEmail",employeeEmail).first().now();

Do i load my entity faster using key?

Answer 1

Yes, loading by key is faster and cheaper. You avoid an unnecessary index lookup.
