Imports
io.netty5.channel.ChannelFactory, .EventLoop, io.netty5.channel.socket.DatagramChannel, io.netty5.resolver.AddressResolver, .AddressResolverGroup, .NameResolver, .RoundRobinInetAddressResolver, java.net.InetAddress, .InetSocketAddress
A AddressResolverGroup of DnsNameResolvers that supports random selection of destination addresses if multiple are provided by the nameserver. This is ideal for use in applications that use a pool of connections, for which connecting to a single resolved address would be inefficient.

Method Summary

Modifier and TypeMethod and Description
protected final AddressResolver<InetSocketAddress>
newAddressResolver(EventLoop eventLoop, NameResolver<InetAddress> resolver)

Overrides io.netty5.resolver.dns.DnsAddressResolverGroup.newAddressResolver.

We need to override this method, not newNameResolver(EventLoop, ChannelFactory, DnsServerAddressStreamProvider), because we need to eliminate possible caching of io.netty5.resolver.NameResolver#resolve by InflightNameResolver created in newResolver(EventLoop, ChannelFactory, DnsServerAddressStreamProvider).
