Reactive Mythbusters With Reactor
summary
Nine concrete claims get tested with live coding using Reactor and Spring WebFlux across examples that translate imperative loops into Flux.fromIterable chains, show the missing subscribe and the need to block (countdown latch or blockLast), and demonstrate concatMap, delayUntil/elapsed, zipWith for per-item random delays and ranking. Outcomes: learning curve confirmed, inherent complexity mostly busted, operator set is empowering not limiting, implementing JDK 9 Flow publishers is surprisingly hard, testing works well with StepVerifier with virtualTime and debugging improves with checkpoint, and blocking can make unrelated work stall.
