I don't think Google has some magic "make this algorithm scale to huge datasets" box that they can run things through. The reason why Google can run predictions on huge datasets is because they designed an algorithm that has lower accuracy but greater scalability; this service seems to be just them giving you an API to that algorithm. I think your comment sounds like "I like your algorithm, but I'd rather use my algorithm, so please run my algorithm but make it have the features of your algorithm"...
