[jira] [Comment Edited] (FLINK-29913) Shared state would be discarded by mistake when maxConcurrentCheckpoint>1

    [ https://issues.apache.org/jira/browse/FLINK-29913?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17629771#comment-17629771 ]

--------------------------------------------------------------

[~klion26] Since maxConcurrentCheckpoint>1 &&MAX_RETAINED_CHECKPOINTS>1  are less frequently used, I set the priority to Minor.
Under the current checkpoint registration and deletion mechanism, I think this bug will take a while to fix, I'd like to fix this problem after discussion.
