> Currently persistent cache if enabled for nodes caches all nodes accessed on
> the system. It would be better if it can be configured to only cache those
> nodes which are not volatile so that caching can be effective
> Purpose of this issue is to
> * Provide an extension point in PersistentCache logic to check if a node is
> to be cached
> * Provide an impl which relies on some static OSGi config to determine that
> Later we can make this impl dynamic i.e. rely on access pattern to cache imp
> stuff
