Various suggestions but overall this looks like a great improvement. I think many of these suggestions were issues present in the previous iteration as well.

| Use `StreamingDataLoader` when you want multi-worker prefetch and exact resumability. It carries a state snapshot | ||

In this case, use `StreamingDataLoader` for multi-worker prefetch and exact resumability. It carries a state snapshot |

Improvements to data loading documentation, as part of Jason's internship project. Reorganized the "Data Loading" tab of the public-facing documentation, and added new section regarding 2-phase shuffled read. Slack me with questions
