ChannelPerResolver
Use the same underlyingChannel
for all queries produced by a singleDnsNameResolver
instance. -
ChannelPerResolution
Use a newChannel
per resolution or per explicit query. As of today this is similar to what theDefaultNameResolver
(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.
