Hi SubstantialElk6 ,
That's an interesting idea. I think if you want to preprocess a lot of data I think the best would be using multiple datasets (each per process) or different versions of datasets. Although I think you can also pull specific chunks of dataset and then you can use just the one - I'm not sure about the last point.
What do you think?
I think this might also be helpful. Gloss over the functions available in the documentation, I think you might find what you're looking for 🙂
