Michael Dürig commented on OAK-2586:
------------------------------------

It might not be too bad as {{JackrabbitNodeState}} doesn't have an optimised 
{{equals}} implementation neither. But we should definitely benchmark it 
against the current implementation with a large repository.

> When upgrading a Jackrabbit 2 to an Oak repository it can be desirable to 
> constrain which paths/sub-trees should be copied from the source repository. 
> Not least because this can (drastically) reduce the amount of content that 
> needs to be traversed, copied and indexed.
> I suggest to allow filtering the content visible from the source repository 
> by wrapping the JackrabbitNodeState instance and hiding selected paths.
