Map Clojure async tools to familiar CompletableFuture patterns and pick the simplest option.
If you know CompletableFuture, you already understand a lot of async design: representing work that completes later, composing stages, handling failure, and choosing an execution policy.
This section maps those ideas to common Clojure tools—future, promise, channels, and event-driven designs—and explains where the semantics differ (blocking deref, cancellation, error propagation, and backpressure).
The practical goal is to help you choose the smallest tool that keeps the code easy to read.
