用于CompletableFuture的Spark流

Question

可以在Spark Streaming处理过程中从CompletableFuture's开始进行流传输，例如，我们有3个CompletableFuture作为波纹管：

        final CompletableFuture<String> CF_A = 
CompletableFuture.supplyAsync(() -> {method_A();    return "A"; });


        final CompletableFuture<String> CF_B = 
CompletableFuture.supplyAsync(() -> {method_B();    return "B"; });


        final CompletableFuture<String> CF_C = 
CompletableFuture.supplyAsync(() -> {method_C();    return "C"; });

    CompletableFuture
    .supplyAsync(() -> Stream.of( CF_A, CF_B, CF_C )
            .parallel()
            .map(future -> future.join()).collect(Collectors.toList()), executor));

假设方法：method_A(), method_B(), method_C()对文件夹中的某些数据进行过滤，然后每10秒保存一次，

是否可以对此Streaming进行CompletableFuture parallel process？
