The bean name of a default AsyncTaskExecutor to use when a controller method returns a {@link Callable}.
Controller methods can override this default on a per-request basis by returning an AsyncTask.
By default a SimpleAsyncTaskExecutor is used which does not re-use threads and is not recommended for production.

Specify the amount of time, in milliseconds, before asynchronous request handling times out.
In Servlet 3, the timeout begins after the main request processing thread has exited and ends when the request is dispatched again for further processing of the concurrently produced result.
If this value is not set, the default timeout of the underlying implementation is used, e.g. 10 seconds on Tomcat with Servlet 3.
