It looks like datastore in GAE but without ORM (object relation model). May I used the same ORM model as datastore on GAE for Cloud Datastore? or Is there any ORM support can be found for Cloud Datastore?
Google Cloud Datastore only provides a low-level API (proto and json) to send datastore RPCs.
NDB and similar higher level libraries could be adapted to use a lower level wrapper like googledatastore (reference) instead of google.appengine.datastore.datastore_rpc
