Note that by default there is *no expiration* for the cache values,
meaning once a particular setting is cached, that value will never
expire, and therefore the setting will never be re-fetched from DB
(unless a new value is written for it, in which case the cache is
invalidated for that setting, which causes a re-fetch next time it's
requested). You may want values to expire after say, an hour, so that
settings will periodically be re-fetched regardless of write activity.
Do that by specifying the number of seconds after which values should
expire::
[rattail.config]
# nb. expire values after 1 hour
beaker_cache.expire = 3600
