Have you tried the preview of the new bulkloader at http://bulkloadersample.appspot.com/ ? It has an example of this.
However it will export just the key--you can then download both A and B and join them later. Are you trying to export a nested data structure into a hierarchical data format? If so, you need some way to download both kinds. If you exporter (using either system) dereferences the property using a model class, the remote_api connection will download it. Note that this will have a significant performance impact. I'm curious what your expected use case is, as nested data is an interesting and complex case. --Matthew On Apr 26, 3:30 am, "Nick Johnson (Google)" <[email protected]> wrote: > Hi Kartik, > > What do you mean by 'junk values'?
