In today’s world enterprise applications increasingly require the ability to asynchronously process large datasets. The processing of data must correlate and compute results at the same time. This article illustrates how CyclicBarrier and CompletableFuture, combined, perform efficiently in processing and p...
to wait for its completion, and to retrieve the result of the computation. In simple terms, a future is promise to hold the result of some operation once that operation completes.Futurewas introduced in Java 5.
17.12.1 Asynchronous Processing in Servlets Java EE provides asynchronous processing support for servlets and filters. If a servlet or a filter reaches a potentially blocking operation when processing a request, it can assign the operation to an asynchronous execution context and return the thread asso...
The whole point of asynchronous processing is avoid blocking threads. Standard java.util.concurrent.Future does not allow registering callbacks when computation is done - so you either need to devote one thread to block until future is done or use one thread to poll several futures periodically. ...
Another contributing factor to choose Project Reactor over RxJava was that Project Reactor uses Java 8 but RxJava, at the time, was still at Java 7. Project Reactor also offers a rich set of operators that are composable and allow you to write declarative code for building data processing ...

Asynchronous Streaming Request Processing in Spring MVC 4.2 + Spring Boot(SpringBoot中 With the release of Spring 4.2 version, Three new classes have been introduced to handle Requests Asynchronously of the Servlet Thread. Which are; ResponseBodyEmitter...
AsyncHttpClient(AHC) is a library build on top ofNetty, with the purpose of easily executing HTTP requests and processing responses asynchronously. In this article, we’ll present how to configure and use the HTTP client, how to execute a request and process the response using AHC. ...
