How to find out no. of threads operating in Spring Batch

[sumitpramanik]

Hi ,
I have created a sample code in spring batch to implement multithreading , but I am not sure how many threads are getting created .Is there a way to find it out .Is the attribute "throttle-limit" describe the no. of threads that is running ?

Assuming you are referring to using a multithreaded step. In this case, the throttle limit is one indicator of how many threads are running. The other indicator is the number of threads your TaskExecutor is configured to use (if it's using a thread pool for example). Typically, the number of threads running will be the least of these two values (if you set a thread pool to have 2 threads and throttle-limit to 4, you'll have 2 threads running and if you have a thread pool of 4 and a throttle-limit of 20 you'll have 4 running.
