interesting.... i as skim the NDB docs very quickly and the patch above i
see that it is *very* similar to the "DB Datastore"/Big Table. if the APIs
are the same then we should just use the same DAL adapter with a parameter
to use NDB. Though because of the caching nature of NDB there may be a
whole set of additional/different methods that need to be supported.
Saisha D: yes, the google:datastore in web2py currently is using the type
of DB storage that you linked to (the only type of storage supported when
web2py first integrated with GAE).
