[jira] [Commented] (OAK-2726) Avoid repository traversal for trivial node type changes

    [ https://issues.apache.org/jira/browse/OAK-2726?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14499616#comment-14499616 ] 

Julian Reschke commented on OAK-2726:
-------------------------------------

The relevant code appears to be in org.apache.jackrabbit.spi.commons.nodetype.NodeTypeDefDiff; is there a way to use this code directly or do we need a separate Oak variant?

> The {{TypeEditor}} in oak-core checks the repository content when a node type changes to make sure the content still conforms to the updated node type. For a repository with a lot of nodes, this check can take quite a bit of time.
> Jackrabbit has an optimization in place for trivial node type changes. E.g. it will not check the content if a non-mandatory item is added to an existing node type definition. This optimization could be implemented in Oak as well.
