JAX-RS 2.1 Reloaded

on YouTube ↗50m

" summary

JAX-RS 2.1 adds concrete async/reactive pieces: direct support for CompletionStage (JDK 8) and an extension point to plug libraries like RxJava, a new client/server SSE API with SseEventSource and SseBroadcaster types, and a proposal to enable Flow-based non-blocking I/O (publisher/subscriber/processor model) for streaming collections and large payloads. Existing StreamingOutput stays blocking so the new flow types target real NIO integration; work targets a public release around mid‑2017 with adapters for third‑party flow types.
