While synchronous APIs are still used for the vast majority of applications running on JVM, asynchronous, non-blocking programming models are gaining popularity, especially within microservices space, where inter-service calls are remote by definition and blocking can be very detrimental for application performance.

CompletableFuture enables async, promise-based programming in Java, and is probably one of the most powerful and most overlooked additions to Java 8, but it is not the only game in town. Reactive frameworks, such as RxJava and Spring Reactor provide some of the same features and more.

This BOF would allow the attendees to discuss their experiences using any of these async frameworks, compare and contrast the available options, and when it makes more sense to use one over the other.
