This smells bad architecture to me. Been there, seen that many times. That load could be decreased by factor of 10 by some simple clever ideas and changes. Then it could further be lowered. I just can't imagine a map app and a supporting business to be _that_ demanding in terms of storage use. I do see congestion points, but it's not storage.

Unless they're adding up cache lookups to the overall number, which is then just a clickbait.
