DNS Resolver rotate feature about trust-dns HOT 5 OPEN

yes, this would be a nice feature to add. I think it's also related to #1924, as this could be used in the forwarding hickory-dns server.

To make this accurate it would probably mean recording some stats on each RRSet and it's use in the cache, which I don't think we do today. That said, I think randomizing the order of the addresses is also something that the calling code can do. I've always been a little uncomfortable with changing RRSets from what was returned upstream, but I'm not a purest on this.

If you wanted to post something up, maybe even keeping it simple for now by just randomizing the order of the records in the result from the cache, that would be interesting to see.

Hey Benjamin, thanks for your reply :)

Ah I didn't know hickory also provided DNS server capability, I was just using it as a resolver to call DNS server.

I think having a feature where you select a random record in the DNS cache if cache item has multiple records sounds like a great start. Perhaps hickory-resolver users would find that this is good enough for their use-case with short enough TTL. And later we can add round robin.

I am new to this repo and wonder how features are prioritized and released, what is next?

we basically include things as they're ready and then publish in the next release. We're working on a new 0.25 release that will probably come once we have all of the related crates that use ring and rustls updated. So that will come as soon as some of our dependencies are updated.

Something to consider when implementing this, perhaps it could be included only in the RRSet returned by the lookup function... i.e. that way it would make it something like lookup_ip(...).await?.randomized().next()

I see, then I will keep an eye on this feature request. Thanks again!
