Not associated with google, also not an expert on ndb As far as I know key groups are related with consistency, in my opinion, you shouldn't put article's and author's in the same group, there is a 1/s write speed limit on entity groups, if you put them in the same entity group, you could hit this limit more easily
You don't even have to use referenceproperty's - I would just put the author key in an article StringProperty named "author" and query for it, if I were you -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
