   Good.

   I agree on this point. What have you pointed out in the cache here? I'm very 
interested in how we can manage the cache to keep the dataset schema consistent 
between the namespace implementation and the schema metadata in the filepath. 
Till now, there are no mechanisms like a hook to detect the changes in the file 
path schema metadata. I'm curious about it.
