Overview
The session covers the following key aspects related to data lineage:
-
Importance of Data Lineage:
- Data lineage is crucial for organizations to understand where data is coming from, how it's being used, and the impact of any changes.
- It helps address challenges like data siloes, lack of communication, and documentation across various teams and technologies.
-
Open Lineage Framework:
- Open Lineage is a standard specification and protocol for capturing data lineage across different data processing frameworks and tools.
- It allows producers (e.g., Spark, Airflow, dbt) to emit lineage information in a standardized format, and consumers (e.g., AWS Data Catalog) to integrate with it.
- This reduces the need for individual integrations between producers and consumers, promoting interoperability.
-
AWS Data Catalog Lineage:
- AWS Data Catalog has integrated with the Open Lineage framework to provide data lineage capabilities in its product, AWS Data Zone.
- Data Zone aims to address four key themes around data lineage: trust, impact analysis, troubleshooting, and governance.
- It captures lineage information from various sources like AWS Glue and Amazon Redshift, and provides a visual interface to explore the lineage.
- Data Zone also supports column-level lineage and versioning to facilitate detailed root cause analysis.
-
Customer Use Case: San Diego Gas & Electric (SDG&E):
- SDG&E has adopted a data mesh architecture on AWS to manage their complex, siloed data landscape.
- They have leveraged AWS Data Zone and the Open Lineage framework to establish data lineage, not only for data in AWS but also for on-premises data sources.
- This has enabled them to improve data compliance, build trusted data products, and accelerate data-driven decision-making across the organization.
Key Takeaways
- Data lineage is crucial for organizations to understand the provenance and movement of data, enabling better data governance, compliance, and data-driven decision-making.
- The Open Lineage framework provides a standardized way for data producers and consumers to integrate and capture lineage information, promoting interoperability.
- AWS Data Zone, powered by the Open Lineage framework, offers a comprehensive data lineage solution that addresses key use cases around trust, impact analysis, troubleshooting, and governance.
- Customers like SDG&E have successfully leveraged AWS Data Zone and Open Lineage to establish data lineage across their hybrid data landscape, accelerating their data-driven transformation.
Conclusion
The session highlighted the importance of data lineage, the Open Lineage framework, and how AWS Data Zone leverages it to provide a robust data lineage solution. The customer use case from SDG&E demonstrated the practical benefits of implementing data lineage in a complex, hybrid data environment.
