Clojars provides a few static data feeds[1]:

- a list of poms in the repo (all-poms.txt.gz)
- a list of all releases in the repo (all-jars.clj.gz)
- an expanded list of releases, including more metadata from the poms
(feed.clj.gz)

We're evaluating our bandwidth usage in anticipation of moving the
repository to a CDN to improve availability, and noticed some odd
request patterns for these feeds.

There are sites/services out there that make (sometimes heavy) use of
these feeds, so I want to point out that they are only updated hourly,
so requesting them more often gives you no benefit. Even though it's
only 1.4MB in size, feed.clj.gz alone accounted for ~20% (~200GB) of
Clojars' bandwidth usage for the past month, with one client
requesting it 30 times *per minute*.

So if you (or someone you love) uses one of these feeds, can you
confirm that you are caching a copy for at least an hour before
retrieving the latest version?

Thanks!
