Reconnect after server restart

Dear RSocket team,

First of all, I am playing with rsocket. It looks great so far. This is more of a question. This is a very simple spring boot service class for rsocket client. As you see we establish rsocket connection as part of constructor, cache the requestorMono. The below code works perfectly fine as long as server is not restarted. When you restart server, the connection is broken. Client needs to be restarted to make this work. The retry in the ping chain will NOT help as it is cached already. Is there any built in approach in rsocket to handle this?

@Service
public class RSocketPingService {

    private final Mono<RSocketRequester> requesterMono;

    // Spring Boot is creating an auto-configured RSocketRequester.Builder bean
    public RSocketPingService(RSocketRequester.Builder builder) {
        this.requesterMono = builder
                .dataMimeType(MediaType.APPLICATION_CBOR)
                .connectTcp("localhost", 7000).retry(5).cache();
    }

    public Mono<String> ping() {
        return this.requesterMono.flatMap(requester -> requester.route("pong")
                .data("TEST")
                .retrieveMono(String.class));
    }

}

Hello @uselvvi!

It is great to get more users on board!

Have you looked at build-in reconnect feature which does exactly what you need:

@Service
public class RSocketPingService {

    private final Mono<RSocketRequester> requesterMono;

    // Spring Boot is creating an auto-configured RSocketRequester.Builder bean
    public RSocketPingService(RSocketRequester.Builder builder) {
        this.requesterMono = builder
                .rsocketConnector(connector -> connector.reconnect(Retry.backoff(10, Duration.ofMillis(500)))
                .dataMimeType(MediaType.APPLICATION_CBOR)
                .connectTcp("localhost", 7000);
    }

    public Mono<String> ping() {
        return this.requesterMono.flatMap(requester -> requester.route("pong")
                .data("TEST")
                .retrieveMono(String.class));
    }

}

@nbabic298 I just checked the SO answer as well. It seems to match with what I have in this repo as well. Check your version. I use 2.3.2.RELEASE.
