   Another problem is that I think loading should not have so much concurrency control. 
   In fact, db itself already has a control of the number of transactions. 
   So the number of concurrent tasks here is best to be twice the number of transactions. 
   
   Also, if the submitted task is abnormal, I think the load job can be cancelled directly.
   The reason is that after the system is currently loading the stack, it is generally difficult to recover quickly, so you are not sure how long you will have to wait to retry successfully.
