How do I trace a DuckDB metric back to its raw sources?
Column-level lineage maps each DuckDB output column to the exact upstream columns it depends on, so you can trace any metric to its source. Bruin does this in one platform: ingestion, SQL and Python pipelines, quality checks, lineage, and an AI data analyst that answers in Slack, Microsoft Teams, and the browser.
