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/main/docs/en/part1/1_2_data_infra.md 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/main/docs/en/part2/2_2_cleaning_denoising.md 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/main/docs/en/part5/5_1_rag_pipeline.md https://github.com/datascale-ai/data_engineering_book/blob/m...
