Feature Request: First class way to open connects to specific hosts of a service

[leonz]

Dialogue has some cool utilities and abstractions that make it easy to create and reuse clients per-service, but nothing to help with creating clients if you need to create connections to specific nodes/hosts of a service.

This is a use case that we regularly run into with Cassandra and any services that interact with it at a management level.

@leonz I actually recently added a PerHostClientFactory so you can turn a list of uris into a list of channels:

dialogue/dialogue-clients/src/main/java/com/palantir/dialogue/clients/DialogueClients.java

Lines 80 to 86 in 46dc7d9

	public interface PerHostClientFactory {
	/** Single-uri channels. */
	Refreshable<List<Channel>> getPerHostChannels();
	<T> Refreshable<List<T>> getPerHost(Class<T> clientInterface);
	}

.

Do you think this could work for your use-case?

Hi Dan,

Thanks for that! Is there a reason that the interface returns a list of channels rather than a map of hosts to channel?
