聊聊reactive streams的parallel flux

    @Test
    public void testParallelRunOn(){
        Flux.range(1, 1000)
                .log()
                .parallel(8)
                .runOn(Schedulers.parallel()) //parallel flux
                .sequential() //必须使用sequential来将这些异步线程的执行结果汇集成一个stream
                .map(e -> {
                    LOGGER.info("map thread:{},e:{}",Thread.currentThread().getName(),e);
                    return e*10;
                })
                .subscribe(e -> {
                    LOGGER.info("subscribe thread:{},e:{}",Thread.currentThread().getName(),e);
                });
