In a Spring webflux, how to use Ractor Mono/Flux in a data loader

[hantsy]

I tried to use DataLoaders in a Spring WebFlux application, all the APIs in the service/repositories returned a Mono/Flux, but there is no a DataLoader variant for these case.

        BatchLoader<String, Data> batchLoader =new BatchLoader<>() {
            @Override
            public CompletionStage<List<Data>> load(List<String> keys) {
                Mono<List<Data>> monoOfData = loadData(keys);
                CompletableFuture<List<Data>> cfOfData = monoOfData.toFuture();
                return cfOfData;
            }
        };

Monos can be made into CompletableFutures
