In this section, we're going to take a look at using a ManagedExecutorService instance for asynchronous request processing. I'm going to show you how to use CompletableFuture to run and resume asynchronous requests. We will talk about using a TimeoutHandler instance for fine-grained timer control, and we'll be using CompletionCallback and ConnectionCallback instances for even further control of the request processing.
Let's get started and switch to code. As usual, we prepare a template project to get started. The first thing we want to do is use a ManagedExecutorService instance. Thus, we will inject this instance into our REST resource:
@Resource
private ManagedEcecutorService executorService;
Then, we want to use this ManagedExecutorService instance to do some heavy processing, such as processing...
