To improve Java Future, Java 8 provides CompletableFuture which can execute some code whenever its ready. In this article, we’re gonna take a look at new Java 9 CompletableFuture API that supports delay and timeout.
For Scaling & Parallel Processing, Spring Batch provides various solutions: Multi-threaded Step, Parallel Steps, Remote Chunking of Step & Partitioning a Step. In the tutorial, JavaSampleApproach will introduce Partitioning a Step cleary by a sample project.
For scaling a heavy system, Java provides a mechanics for executing expensive jobs in background with Java Thread Pool & Future to manage the final results. Spring Framework makes it more easy with annotation @Async. In the How to start Spring Async with Spring Boot, JavaSampleApproach will guide you how to build asynchronized services with @Async & Spring Boot.
Java Thread Pool is a performance solution for scaling system, so JavaSampleApproach will guide you how to work with Java Thread Pool by ExecutorService and Executors.
In multithreaded programming, Java Future with Callable is very important for tasks which we want to know status and get the returned object.
This article give us an example for how to work with Future and Callable inside.
Callable is a Java interface that is an useful methodology for control multi-threading returns on concurrency development.
The tutorial will guide you to build a concurrency program with ThreadPoolTaskExecutor of Spring Framework and Callable interface.
