If that is the case is is possible to batch them, or limit the number of metadata requests per batch ? If you start getting 429 responses, you may as well just cancel the remainder of the requests ?
Is it possible to show where in the code this is handled, just so that I can familiarise myself with it without wasting your time ?
This is what google says on it.
