public enum DnsNameResolverChannelStrategy extends Enum<DnsNameResolverChannelStrategy>
Strategy that influence how Channels are used during queries.
  • Enum Constant Details

    • ChannelPerResolver

      public static final DnsNameResolverChannelStrategy ChannelPerResolver
      Use the same underlying Channel for all queries produced by a single DnsNameResolver instance.
    • ChannelPerResolution

      public static final DnsNameResolverChannelStrategy ChannelPerResolution
      Use a new Channel per resolution or per explicit query. As of today this is similar to what the DefaultNameResolver (JDK default) does. As we will need to open and close a new socket for each resolution it will come with a performance overhead. That said using this strategy should be the most robust and also guard against problems that can arise in kubernetes (or similar) setups.
