DataChain

TL;DR

DataChain is a reality check for devs who think dumping raw files into S3 and pointing an LLM at them is a viable data strategy.

Who is this actually for?

Data engineers and backend devs at mid-to-large companies who are tired of their AI agents hallucinating because they lack basic database context.

The Good

• Focuses on the unsexy but critical reality of metadata, schemas, and data lineage.
• Validates the need for a semantic layer instead of just throwing more compute at the problem.

The Catch (Potential Downsides)

It adds another layer of infrastructure debt you'll have to manage and pay for. It also assumes your organization actually has the discipline to maintain a clean semantic layer in the first place.
