Reactive systems expect that components will fail eventually and design loosely-coupled systems that can remain active even if several individual parts stop working. Your case works well. Where Spring MVC implements synchronous, blocking I/O, Spring WebFlux implements reactive programming via Reactive Streams. These messages keep different components informed about failures and help them delegate workflow to components that can handle it.
