> Check if a DAV-Request has a Label in the header, before checking if it's

> Key: JCR-3004
> URL: https://issues.apache.org/jira/browse/JCR-3004
> Project: Jackrabbit Content Repository
> Issue Type: Improvement
> Components: jackrabbit-jcr-server
> Affects Versions: 2.2.7, 2.3.0
> Reporter: Christian Stocker
> Assignee: angela
> Fix For: 2.3.0
>
> Attachments: patch_commit_85c91801358a.patch

>
> When looking at our MySQL logs, I realized that jackrabbit on each DAV
> Request calls the VERSION table every time I get a new node (which is not
> cached yet), even if I only do a simple getNode.
> As a versioning table can get pretty large, this may have a performance
> impact.
> I found out, that DavResourceFactoryImpl checks, if a node is versioned to
> decide, if we have to check for the Label header to later check out another
> version for the GET request. I re-ordered those checks now so that it first
> checks, if there's an http Label-header and only then checks, if the node is
> versioned. The check for a Label header should be much faster than checking a
> DB, if it's versioned (and scale much better, too)
