It's worth to think about your rollup/aggregation strategy

For metrics-like errors, its better to show the worst case scenario with max/max

You want to really understand decorators? Watch this video!

boilerplate:

import functools

def decorator(func):
    @functools.wraps(func)
    def wrapper_decorator(*args, **kwargs):
        # Do something before
        value = func(*args, **kwargs)
        # Do something after
        return value
    return wrapper_decorator

Note à moi même : il faut faire attention aux headers qu'on forward à l'origine dans ce cas précis car ça peut poser des problemes d'authent' entre cloudfront et le bucket s3
