This assumes the whole dataset fits on disk in one machine, right? (Fine for LAION since it is just URLs, but probably not in general.)
What's the best way to get data into NeMo Curator? E.g., would it make sense to use Ray Data to read the data and stream it in? Or does NeMo Curator have methods for this?

Since nemo curator uses nvidia DALI, I think the ideal data loading story would be to have all the images in something like s3 partitioned into different tar shards. We can then mount the s3 on each of the nodes, with each node accessing the subset of tar shards that it is computing on. Would you like me to build this into the example?
