java - Schedulers.newElastic和Schedulers.elastic方法之间有什么区别？

我正在研究Flux和Mono，并在多线程环境中使用它们，并使用提供工作线程的Schedular。
有许多选项可以使用elastic，parallel和newElastic启动Schedular。
这是我使用的代码:

    System.out.println("------ elastic ---------  ");
    Flux.range(1, 10)
      .map(i -> i / 2)
      .publishOn(Schedulers.elastic()).log()
      .blockLast();

    System.out.println("------ new elastic ---------  ");
    Flux.range(1, 10)
      .map(i -> i / 2).log()
      .publishOn(Schedulers.newElastic("my")).log()
      .blockLast();

并且它们都有相同的文档:

这是它们两个的日志:

------ elastic ---------

[ INFO] (main) | request(unbounded)
[ INFO] (elastic-2) | onNext(0)

两者有什么区别？

最佳答案

elastic()函数返回一个共享的调度程序实例。这意味着对该函数的多次调用将返回相同的调度程序。

前缀为new的函数将始终创建一个新的调度程序实例。
