Love the docs, good idea :). About rr: why not just use the is_rr()
function consistently, it was added a while ago.
Also, we're having some pretty serious issues around round-robin (we
think), which is a definite regression since 5.3.x. We have a very hacky
solution right now, but overall, a lot of this HostDB stuff either has to be
cleaned up / fixed, or ripped out. As such, how important is the persistent
cache storage to your use case? Seeing that you updated the docs for it, I'm
guessing it's important? In my setup, we basically clear the HostDB on startup
every time, since the on-disk storage is pretty much useless to us.
