Review Comment:
> Could you also tell users how to change the configuretion and the config
name in the exception message?
Thank you for above comments，but I still hava a question. Is there a maximum
limit on this value? If users can configure it as much as possible, there
should be a maximum limit, such as not exceeding the size of taskmanager's
taskmanager. memory. process. size？
Thank you for your reply！
