What Default Thread Pool is Used by FeignClient in SpringBoot when Hystrix is Enabled
To clarify this question, here we have two feign clients:
@FeignClient(name = "student")
public interface StudentFeign {
@GetMapping(value="/v1/student/{id}")
Student getStudent(@PathVariable("id") String id);
}
@FeignClient(name = "teacher")
public interface TeacherFeign {
@GetMapping(value="/v1/teacher/{id}")
Teacher getTeacher(@PathVariable("id") String id);
}
Would the requests of StudentFeign and TeacherFeign are executed in their own isolated thread pools or in the same thread pool?
The issue here is that if they are using the same thread pool, one slow/unstable feign client may consumes all the resources and affects the other.
If they have their own thread pools, it is using bulkhead pattern, which seems safer to me.

I think the threadpool does not depend on tech but on which container you are using. For example, Tomcat by default has 1 threadpool which will be responsible for allocating thread to a dedicated request. The concern about excessive use of resources leads to the implementation of Hystrix. You can configure the slow/unstable feign to fail fast (circuit break) and then it will not consume too much resource of the system.
