Execute fire and forget for long running process

[DevEnol]

Hi!

I need to implement a method that would trigger fire and forget behavior. The code I wrote are something like this:

public Uni<String> startProcess() {
    longRunningProcess().subcribe().with(logger::info(message))
    return Uni.createFrom().item("Processing");
}

public Uni<String> longRunningProcess() {
    //Perform long running task then return with String: "Finished"
}

This code seems to work as my expected behavior. Is this code functioning as intended, or is there room for improvement?
And are there any better ways to implement this?

In general, when I need to do such kind of things, I use the following pattern:

public Uni<String> longRunningProcess() { ... }

// ...

var csJustInCaseINeedToCheck = longRunningProcess()
     .runSubscriptionOn(Infrastructure.getDefaultWorkerPool() // If it's blocking, make sure it does not block the current thread
    .subscribeAsCompletionStage(); // Trigger the operation and return a completion stage so I can check if it completed or failed
