----------------------------------------
[~joerghoh] Can you come up with a proposal?
> DocViewImporter: logIgnoredProtectedProperties can slow down package import
> ---------------------------------------------------------------------------
>
> Key: JCRVLT-809
> URL: https://issues.apache.org/jira/browse/JCRVLT-809
> Project: Jackrabbit FileVault
> Issue Type: Improvement
> Components: Packaging
> Reporter: Joerg Hoh
> Priority: Major
>
> In the case of Sling distribution the packages being created and imported are
> controlled by the framework, and IIUC protected properties are not part of
> the package; for that reason
> {{DocViewImporter.logIgnoredProtectedProperties}} will not write any WARN
> message.
> When checking the details of the import of a complex package (with almost
> 100k nodes and low to medium amount of properties per node), I came
> frequently across this type of stack, where it's checked if properties are
> protected. Commenting the 2 calls to
> {{DocViewImporter.logIgnoredProtectedProperties}} gave me an improvement of
> the import time in the range of 10%.
> For that I think that we should provide a chance to disable these checks,
> preferably via the API, so that it can configured per package I want to
> import. Disabling it globally might not be helpful, as we might have cases,
> where we cannot give the guarantee about no protected properties being part
> of the package(s).

> Alternatively I would also be happy about an optimized version of
> "DocViewImporter.isPropertyProtected", which does not need resolve every
> property all the time from scratch.
> Note: Optimizing {{isPropertyProtected}} might be the prefered way, as it is
> also invoked via the {{DocViewImporter.setUnprotectedProperties}} code path,
> which I also see very frequently in my dumps.
