Single
The Single type represents streams that produce precisely one element. It does not inherit the Publisher interface. It also has the toFlowable method, which, in this case, does not require a backpressure strategy. Single better represents the semantics of CompletableFuture than Reactor's Mono type. However, it still does not start processing before subscription happens.
