Tracking Data Flow
Data lineage shows data journey.
Why It Matters
Debugging: where did bad data come from? Impact analysis: what breaks if we change? Compliance: audit trail.
Components
Sources: where data originates. Transformations: how data changes. Dependencies: what depends on what.
Tools
Apache Atlas, DataHub, Amundsen. OpenLineage standard. Cloud-native: Dataform, dbt.
Key Takeaways
- Lineage enables debugging and impact analysis
- Track sources, transformations, dependencies
- OpenLineage provides standard format
