[jira] [Commented] (SLING-4585) Performance: Use JackrabbitSession#getItemOrNull to speed up JcrResourceProvider#createResource

["Joel Richard (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-4585?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14968773#comment-14968773 ] 

Joel Richard commented on SLING-4585:
-------------------------------------

Unfortunately, I have forgotten to increment the API version of the Jackrabbit API which is why we have to wait another release cycle to get this change in (see JCR-3919).

The good news is that this change will likely be more effective than anticipated for non-admin users because of the ACL overhead which can be reduced (especially GlobPattern.WildcardPattern in Oak).

> If the current session is a JackrabbitSession, JcrResourceProvider should use getItemOrNull (as soon as exported) to save rendering time.
