Mono之间如何正确交互？

Question

I'm new using the Spring Webflux and I was able to join the results between two rest API with the code:

return item.zipWith(children).flatMap(tuple -> {
        tuple.getT1().setItems(tuple.getT2());
        return Mono.just(tuple.getT1());
    });

Item is a Mono and children a Mono<List>. My questions are:

• is this a good implementation or it's a blocking one that waste the feature of Reactive programming?
• There is a better way to do it?
• I couldn't find a clear list of non-blocking/blocking operations, anybody knows if there is one?

Answer 1

In my opinion: If children is List type, it is better to make it as a Flux type is better, and you could use Flux.fromIterable(List) method to transform List to Flux .

Therefor, the children can receive elements and be delivered into item non-blocking.
