Earners of this badge can write Java code using Java CompletableFutures. CompletableFutures allow us to create asynchronous, non-blocking operations, which are an important part of building Reactive systems. Earners understand blocking operations, and how they impact the efficiency of a system. Earners can use CompletableFutures to isolate blocking operations, and and transform those futures over time. Earners can use Executors to control the threadpool that is used to execute a future.
