> Currently the Background Read operation invalidates the complete cache in
> {{MongoNodeStore}} upon detecting external change. Instead of that it should
> check for which cached documents are stale and only invalidate them.
> It can make use of {{_lastRev}} to check if nodes within a subtree have
> changed or not.
