[jira] [Updated] (OAK-511) Query PropertyIndex that stores the index content as nodes

     [ https://issues.apache.org/jira/browse/OAK-511?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alex Parvulescu updated OAK-511:
--------------------------------

    Attachment: OAK-511.patch

attaching proposed patch.

after a short talk with Thomas we came to the conclusion that at least initially the code will be a duplicate of the existing PropertyIndex rather than a direct evolution.

This doesn't mean that we'll keep the old code around much longer, it will just give us a way to bench the old against the new.

Tests look very good.

I'm guessing the NodeTypeIndex could be switched over for some more tests.

> A current limitation of the PropertyIndex is that is stores the index content as multi value properties. This causes merge conflicts when there are concurrent updates to the index.
> A workaround was found to split the mvp into child-nodes. This alleviates the need for diffing the properties reducing the potential conflict area.
