Data Features

Data Lineage

Visualize how data flows through your pipeline — from source tables through transformations to final outputs. Supports table-level and column-level tracking.

What lineage shows you

Lineage answers the question: "Where does this data come from, and what depends on it?" The lineage graph shows directed arrows between tables — an arrow from Table A to Table B means Table B was derived from or references Table A.

Table-level vs column-level lineage

Table-level lineage

Shows which tables feed into which other tables. Good for understanding pipeline architecture.

Column-level lineage

Traces individual columns through transformations. Answers "which source column does this revenue figure come from?"

Impact analysis

Select any table and click Impact Analysis to see what would be affected if that table changed or broke. All downstream tables and columns are highlighted.

Automatic lineage detection requires roles/bigquery.metadataViewer or bigquery.jobs.list permission on the service account.
