hystrix如何创建其线程池(How hystrix creates their thread pool)

 我的应用程序在Websphere Application Server中运行。 我正在使用Hystrix进行一些外部服务调用。 WAS服务器具有线程池配置，例如最大线程池大小为10，HystrixThreadPoolProperties maxCoreSize设置为5。 
 
 我想知道如何通过hystrix管理线程。 hystrix是否从WAS服务器线程池中消耗5个线程，或者它是否会创建自己的线程池，其中包含5个新线程，这将导致总共15个线程。 
 
 在我的情况下，我希望hystrix使用WAS线程池中的线程而不是创建新线程。 请指教。 
 
 提前致谢。 

My application is running in Websphere Application server. And I'm using Hystrix for some external service calls. The WAS server has a thread pool configuration, say a max thread pool size of 10 and the HystrixThreadPoolProperties maxCoreSize is set to 5. 
 
I'm wondering how the threads are managed by hystrix. Does hystrix consumes 5 threads from the WAS server thread pool or will it create its own thread pool with 5 new threads which will result in a total of 15 threads. 
 
In my case, I would want the hystrix to consume the threads from the WAS thread pool rather than creating new threads. Please advice. 
 
Thanks in advance.
