Is the "sub" identifier permanent for particular google account?

I want to use sub identifier to store users (who authorized with GoogleLogin) in my database. But is this sub id permanent for the particular account?

https://developers.google.com/assistant/identity/google-sign-in-oauth as specified here, Google recommends to use sub as an unique user identifier (ID) in database.
