future filed may cause the order to be disrupted. How to solve it

[madwind]

I have a list sorted by vodtime. When I use @schemamapping in spring-graphql , I find that if the return type is Mono, it causes the order to be disrupted.

    searchVideo(searchParams: $searchParams){
      id
      uniqueName
      vodName
      vodYear
      typeName
      vodArea
      vodPics <= SchemaMapping
      vodRemarks
      vodDoubanScore
      vodDoubanId
      vodTime
      lastEpisode <= SchemaMapping
      resources <= SchemaMapping
      isFavorite <= SchemaMapping Mono
    }

    @SubscriptionMapping
    public Flux<Video> searchVideo(@Argument SearchParamsDTO searchParams, @AuthenticationPrincipal User user) {
        return videoService.listVideos(searchParams).doOnNext(video -> System.out.println(video.getVodTime()));
    }

    @SchemaMapping
    public Mono<Boolean> isFavorite(Video video, @AuthenticationPrincipal User user) {
        return favoriteRepository.findByUserIdAndVideoUniqueName(user.getId(), video.getUniqueName())
                .hasElement();
    }

    @SchemaMapping
    public List<String> vodPics(Video video) {
        return video
                .getPlaySources()
                .stream()
                .map(PlaySource::getVodPic)
                .filter(StringUtils::hasText)
                .collect(Collectors.toList());
    }

ts:

console.log("vodTime: " + video.vodTime + ", isFavorite: " + video.isFavorite)

video-list-layout.component.ts:58 vodTime: 2024-04-13 09:22:28, isFavorite: false

If I remove 'isFavorite' in GraphQL, its order will become correct.

    searchVideo(searchParams: $searchParams){
      id
      uniqueName
      vodName
      vodYear
      typeName
      vodArea
      vodPics
      vodRemarks
      vodDoubanScore
      vodDoubanId
      vodTime
      lastEpisode
      resources
#      isFavorite
    }

Hello, letting you know this is the discussion page for GraphQL Java, which is the engine underneath Spring for GraphQL. Spring for GraphQL is a separate project.

Could you repost your question on Stack Overflow with the Spring for GraphQL tag? You might get more answers there. https://stackoverflow.com/questions/tagged/spring-graphql

I've already submitted an issue in the spring-graphql project. Here's the link: spring-projects/spring-graphql#949. @bclozel told me that this seems to be due to graphql-java and conducted some tests, indicating that this problem may not be solvable at the Spring level.

Ok my bad thanks for posting in the Spring project too

#3574 addresses this. I am going to close this discussion because its captured in other ways
