That would solve a major App Engine issue. sorry, i probably got ahead of myself by naming specific calls. naturally, if/when we implement these features, we'd let you set a new entity's id manually, as well as possibly do more specific things to manage id namespaces. we have a decent idea of how we'll implement all this in the datastore backend, but we haven't thought at all about the developer API yet, so you all are ahead of me. :P On Mar 8, 6:28 pm, Andy Freeman <ana...@earthlink.net> wrote: > > I understand why you're considering doing that, but it would also be > nice to have similar operations wrt "no root".
