About This Course

Java 8 introduced us to Java CompletableFutures. CompletableFutures are a way to isolate operations to a separate thread of execution. They allow us to create asynchronous, non-blocking operations, which are an important part of building Reactive systems. They also allow us to isolate blocking operations to their own threadpool which can help reduce contention in the system and improve resource usage.

In this course you will learn about blocking operations, and how they impact the efficiency of your system. You will see how CompletableFutures can be used to isolate blocking operations, and how to transform those futures over time. You will also see how Executors can be used to control the threadpool that is used to execute a future.
