重连尝试之间暂停

It doesn’t make much sense to try to connect to the same server over and over. To prevent this sort of thrashing, and wasted reconnect attempts, especially when using TLS, libraries provide a wait setting. Generally clients make sure that between two reconnect attempts to the same server at least a certain amount of time has passed. The concrete implementation depends on the library used.

This setting not only prevents wasting client resources, it also alleviates a thundering herd situation when additional servers are not available.

// Set reconnect interval to 10 seconds
nc, err := nats.Connect("demo.nats.io", nats.ReconnectWait(10*time.Second))
if err != nil {
    log.Fatal(err)
}
defer nc.Close()

// Do something with the connection
