I have different python classes and all of them having a method called push. What I am trying to is

1. Create multiple class objects one from each class
2. Call push method
3. All these methods should execute in parallel
4. Log messages coming from push method as and when its complete
5. Wait for all the methods to complete and exit scrip

I have tried multiple ways using

    def push_wrapper(obj):
        obj.push()
    
    
    class_objects=[class1_obj1,class2_obj2,class3_obj3]
    with Pool(processes=max_thread_count) as pool:
        pool.map(push_wrapper, class_objects)
        pool.close()
        pool.join()

With this getting getting this error raise TypeError(f"cannot pickle {self.__class__.__name__!r} object")

There are some other approaches like using pool.apply_async but they are not waiting for all the methods to complete exiting immediately . When i add job.wait() along with pool.apply_async its waiting for all threads to complete but I want to print result of the thread as and when its complete

Let me know what is the best approach to address this use case
