In the google io talk, data join is implemented by Append method. But it seems the Append method is only to append lists together. Is that Append method just a high-level concept or is there an implementation?
Also, join can be implemented by using referenceProperty. It is not necessary to do the map first, and append sets of the map results together. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
