>
> datastoreio discards the entity key and just returns a collection of decoded
> entities.
> This might work for some use cases but often you need to know the key of the
> entity you're operating on, e.g. if you need to update it or store a
> reference to it.
> Maybe it should return a PCollection<*datastore.Key, T> instead of just
> PCollection<T>?
> Or PCollection<string, T> using key.Encode(), since the go sdk doesn't seem
> to support pointers yet.
