Google App Engine Will the data warehouse object identifier be negative?

Question

Will the data warehouse object identifier be negative? Or are they guaranteed to be positive numbers?

Answer 1

No.

Additional text to make my answer so happy.

Answer 2

I cannot find a document expressly declaring this, but I have never seen a negative. docs say that the identifier usually increases as new objects are created. (But you should not rely on them strictly, since you can move away a little from the order, for example, 10,11,13,12,14)
