Schedulers.io()和 Schedulers.computation()有什么区别?

推荐答案

来自 rx文档:

Schedulers.computation() -用于诸如事件循环和回调处理之类的计算工作；不要将此调度程序用于I/O(改为使用Schedulers.io())；默认情况下，线程数等于处理器数

Schedulers.computation( ) - meant for computational work such as event-loops and callback processing; do not use this scheduler for I/O (use Schedulers.io( ) instead); the number of threads, by default, is equal to the number of processors

---

Schedulers.io() -用于进行I/O绑定的工作，例如阻塞I/O的异步性能，此调度程序由线程池支持，该线程池将根据需要增长；对于普通的计算工作，请切换到Schedulers.computation();.Schedulers.io()默认为CachedThreadScheduler，类似于带有线程缓存的新线程调度程序

Schedulers.io( ) - meant for I/O-bound work such as asynchronous performance of blocking I/O, this scheduler is backed by a thread-pool that will grow as needed; for ordinary computational work, switch to Schedulers.computation( ); Schedulers.io( ) by default is a CachedThreadScheduler, which is something like a new thread scheduler with thread caching
