Hi Neal, hi Thread,
This is a legit concern yet majority of people appreciates having the
metadata handy and only a minority worries about the traffic.
Downloading the data *every hour* is overkill though. Once a day
should be more then enough.
Not necessarily, it depends on how quickly are old packages removed from
the mirrors, the minimum is not dictated by anyone. The metadata expiry
time could be used as the lower bound on this but then there could be
repos that have this set to less than an hour for instance. In any case:
this value is inspected on every 'dnf makecache' execution so for normal
repositories that only expire once a day or so nothing is downloaded 96%
of the time. Note that the Fedora update repositories expire every 6 hours.
All that said, we shouldn't bother with pathological cases like that and
only run the metadata check every six hours or less often. So,
basically, you are right.
Ales
