Is there a way to query all the vectors and/or metadata from a namespace ?

Would you happen to have a snippet? Trying to make the same thing.

I ended up hacking something together using the scripts from here and added on this helper to extract that dynamic id key:

def get_first_item(my_dict):
    if my_dict:
        first_key = next(iter(my_dict))
        return my_dict[first_key]
        return None
