# Token server doesn't provide a new a token when doing refresh unless the
# token is expiring within 30 seconds, so refresh threshold should not be
# more than 30 seconds. Otherwise auth lib will send tons of refresh requests
# until 30 seconds before the expiration, and cause a spike of CPU usage.
REFRESH_THRESHOLD = datetime.timedelta(seconds=20)
# The smallest MDS cache used by this library stores tokens until 4 minutes from
# expiry.
REFRESH_THRESHOLD = datetime.timedelta(minutes=3, seconds=45)
