"Project Nessie: Transactional Catalog for Data Lakes with Git-like Semantics"

https://projectnessie.org/

This supports lightweight branches, and transactional commits and merges. I haven't used it—and it seems cool—but it also seems a little heavyweight to get cross-table transactions on top of these table formats (which would be my primary use case).

[Disclosure: I designed and wrote most of the docs for TensorFlow’s Dataset API.]

I’m sorry to hear that you’ve not had a pleasant experience with tf.data. One of the doc-related criticisms we’ve heard is that they aim for broad coverage, rather than being examples you can drop in to your project and run straight away. We’re trying to address that with more tutorials and blog posts, and it’d be great if you started a blog on that topic to help out the community!

If there are other areas where we could improve, I’d be delighted to hear suggestions (and accept PRs).
