[jira] [Updated] (OAK-5113) Avoid dispatching changes for checkpoint related changes

["Chetan Mehrotra (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/OAK-5113?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Chetan Mehrotra updated OAK-5113:
---------------------------------
    Attachment: OAK-5113-v1.patch

[patch|^OAK-5113-v1.patch] for the same (for segment-tar for now). Its conservative in the sense that only for {{refreshHead}} call *after* CP related changes are done do not dispatch changes. In all other cases changes are dispatched.

With this and OAK-4935 all no change gets added to the observation queues!

> As discussed [here|https://issues.apache.org/jira/browse/OAK-4935?focusedCommentId=15666420&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15666420] {{SegmentNodeStore}} currently dispatches changes even for checkpoint related operations. Given these changes are under super root and not affect the tree under normal root we can avoid dispatching such changes at all
