Views are more of a convenience, conceptually it's just an index though. Could you please elaborate more on the `Index` please? What is it, and how does it fit? What...

Closing as this does not look like a bug in dvc, but is more of a documentation issue.

This should be ready for review. The above asciinema is stale (although the only change is removal of `--type` with `dvcx://`, `dvc://` and `dvc+https://` schema). And support for pipelines with...

Updated the asciinema recording above.
