Xin Chen commented on FLINK-23352:
----------------------------------

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 anyone's reply!
