HN discussionWe actually built a tool exactly for that: https://www.datafold.com/data-diff The core use case is helping data engineers building analytical pipelines test the changes to their code prior to deploying, but can also work for any query. You can diff tables or just SQL queries directly.

HN discussionLooks great! Congrats on the launch. How does this differ from a data reliability platform like Datafold? https://www.datafold.com/ And can this replace what https://atlan.com/ does as well?

I'm particularly glad they mentioned the dbt-ut…

Just looking at the video I could not figure out what's differentiated. I hope you have success in the space. [1] https://www.datafold.com

on “Ask HN: How do you test SQL?”I did data engineering for 6 years and am building a company to automate SQL validation for dbt users. First, by “testing SQL pipelines”, I assume you mean testing changes to SQL code as part of the development workflow? (vs. monitoring pipelines in production for failures / anomalies). If so: 1 – assertions. dbt comes with a solid built-in testing framework [1] for expressing assertions such as “this column should…
