Which columns in this table are never used downstream?
Lineage shows columns with no downstream consumers, so you can safely deprecate them and shrink your models. 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.
