Coroutines and Reactive Programming - Friends or Foes?
summary
Compares Kotlin coroutines with Reactor reactive programming using concrete code and tradeoffs: chooses Reactor (Mono, Flux) as the reactive example, shows when coroutines keep simple sequential async code readable and when Reactor’s pipeline operators and backpressure shine for streams. Demonstrates coroutine features: coroutine Dispatchers and withContext, async/await with structured concurrency, channels (hot streams) versus Flux (cold/hot), retry policies (example: exponential backoff up to 5 attempts) and interop adapters.
