    I'm not sure whether this is an artefact of translation, but things like this don't inspire confidence:

    > The "Modern Data Stack" (MDS) is a hot concept in data engineering in recent years, referring to a cloud-native, modular, decoupled combination of data infrastructure

    https://github.com/datascale-ai/data_engineering_book/blob/m...

    Later parts are better and more to the point though: https://github.com/datascale-ai/data_engineering_book/blob/m...

    Edit: perhaps I judged to early. The RAG sections isn't bad either: https://github.com/datascale-ai/data_engineering_book/blob/m...

      Appreciate the honest feedback.

    I'd have titled the submission 'Data Engineering for LLMs...' as it is focused on that.

    • xx123122 27 minutes ago

      That's a great point. I completely agree—'Data Engineering for LLMs' is much more accurate given the content.I'll pass this feedback on to the project lead immediately. Thanks for the suggestion.

    this is great and i bookmarked it so i can read it later. i’m just curious though, was the readme written by chatgpt? i can’t tell if im paranoid thinking everything is written by chatgpt

      Yes, you are right. We are a team from China and used GPT to help with the English translation. We didn't realize it came across as 'fake warmth.' We appreciate the feedback and will work on making the tone more neutral and concise.

      I think it was. It's a wall of information, lots of summary tables, fake warmth, and has that LLM smell to it. I'd be very surprised if this wasn't generated text.

      Whether it's GPT or not, it needs rewriting.

      Thanks for sharing the direct link! Much appreciated.

      Oh thanks! I've switched the top URL to that now. Submitted URL was https://github.com/datascale-ai/data_engineering_book.

      I hope xx123122 won't mind my mentioning that they emailed us about this post, which originally got caught in a spam filter. I invited them to post a comment giving the background to the project but they probably haven't seen my reply yet. Hopefully soon, given that the post struck a chord!

      Edit: they did, and I've moved that post to the toptext.

        Huge thanks, dang! I really appreciate you rescuing the post from the filter and switching the URL to the English version.And thanks for pinning the context comment; it helps a lot since the project is quite extensive. We're thrilled it struck a chord.

    Parquet alone is not for modern data engineering. Delta, Iceberg should be in the list

      Thanks for the feedback! I've flagged this for the team member working on that section.We are taking a short break for the Chinese New Year, so updates might be a bit slower than usual.QAQ

      Thanks for understanding, and Happy New Year!

    The figures in the different chapters are in english (it's not the case for the image in README_en.md).

    • xx123122 5 hours ago

      Thanks for the heads-up! We noticed that discrepancy as well and have just updated the README_en.md with the correct English diagram. It should be displaying correctly now.

    If you are interested in (2026-)internet scale data engineering challenges (e.g. 10-100s of petabyte processing) challenges and pre-training/mid-training/post-training scale challenges, please send me an email to d+data@krea.ai !

    谢谢

    How is possible a Chinese publication gets to the top in HN?

    • xx123122 5 hours ago

      Thanks for the support! We believe that code and engineering challenges are universal languages.

      We are pleasantly surprised by the warm reception. We know the project (and our English localization) is still a Work in Progress, but we are committed to improving it to meet the high standards of the HN community. We'll keep shipping updates!

      Nevermind.
