[jira] [Comment Edited] (FLINK-24332) Support to mount a dynamically-created persistent volume claim per TaskManager
[ https://issues.apache.org/jira/browse/FLINK-24332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17576582#comment-17576582 ]

--------------------------------------------------------
I have some questions when using statefulset:
# what is the style of statefulset support? All TM use one statefulset? one TM use one statefulset?
# If all TM use one statefulset, how we know how many TM need to create and when to delete TM with no task running?
# If one TM use one statefulset, how we control the statefulset create or delete with dynamic PVC?
