[jira] [Comment Edited] (YARN-9049) Add application submit data to
state store
[ https://issues.apache.org/jira/browse/YARN-9049?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16703500#comment-16703500 ]

--------------------------------------------------------------
Understood. Let me ask this way: forget about implementation details, in general, why would adding future app data entry in _ApplicationData_ be easier than adding it directly in _ApplicationHomeSubCluster_?
I think at API/interface level, the latter makes more sense because _ApplicationHomeSubCluster_ should already serve as _ApplicationData_ (if not renamed to it). If for mysql implementation, the former is easier (by adding a extra layer), then this should be kept implementation specific, and not exposed to the API?
