[jira] [Commented] (OAK-169) Support orderable nodes

    [ https://issues.apache.org/jira/browse/OAK-169?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13407900#comment-13407900 ] 

Michael Marth commented on OAK-169:
-----------------------------------

Would we need to support multi-valued properties with many entries for such an implementation? I wonder about the 10M-child node[1] case when ordering is added.

> There are JCR clients that depend on the ability to explicitly specify the order of child nodes. That functionality is not included in the MicroKernel tree model, so we need to implement it either in oak-core or oak-jcr using something like an extra (hidden) {{oak:childOrder}} property that records the specified ordering of child nodes. A multi-valued string property is probably good enough for this.
