+-- Config file example useable for larger resolver farms
+-- In this case cache should be made as large as possible, and prefetching turned off
+-- as the resolver is busy most of the time.
+-- Alternative is using `etcd` as a configuration backend.
+-- Refer to manual: https://knot-resolver.readthedocs.io/en/latest/daemon.html#configuration
+
+-- Listen on localhost and external interface

+-- Large cache size, so we don't need to flush ever
+-- This can be larger than available RAM, least frequently accessed
+-- records will be paged out as long as there's enough disk space to back it
