Will we be able to handle everything "as-is"?

Future or alternative

What are Futures?

CompletableFuture (Java8+)

Java 8 introduced the CompletableFuture class. Along with the Future interface, it also implemented the CompletionStage interface. This interface defines the contract for an asynchronous computation step that we can combine with other steps.

CompletableFuture is at the same time a building block and a framework, with about 50 different methods for composing, combining, and executing asynchronous computation steps and handling errors.

public Future<String> calculateAsync() throws InterruptedException {
    CompletableFuture<String> completableFuture = new CompletableFuture<>();

    Executors.newCachedThreadPool().submit(() -> {
        Thread.sleep(500);
        completableFuture.complete("Hello");
        return null;
    });

    return completableFuture;
}
