Is there an option to prefetch for Nodelocal DNS Cache

[bennypea]

My current settings for cache is

    cache {
        success 9984 30
        denial 9984 5
    }

If I add the prefetch nothing seems to change.

    cache {
        success 9984 30
        denial 9984 5
        prefetch 1 30s 10%
    }

I cant see prefetched requested in the logs either. I have tested using it using serve_stale which works but is not what I am looking for. At the moment I am going off what is in here: https://coredns.io/plugins/cache/. Is there any documentation you can point me to to understand what I can and cant use for Nodelocal DNS Cache?

Has anyone else successfully used prefetch with nodelocaldns?

Thanks.

I would be very nice with a prefetching function, like unbound has, in node-local-dns, so our applications don't notice cache expirys.
We see an increase (5-10ms) in dns lookup time for the 99 percentile, when a record is expired and node-local-dns has to ask coredns.

The plugin would be included in its entirety, so all plugin configuration options should be available. I am not sure what version of node local DNS you are running, and therefore what version of CoreDNS it is based on. But you could try and make sure vanilla CoreDNS works as you expect?
