Ensuring Data Quality with Data Contracts and OpenLineage

Submitted Jun 10, 2024


In the modern data landscape, ensuring data quality and integrity is paramount. This conference will explore the concept of Data Contracts as a schema registry, incorporating data quality (DQ) checks and leveraging OpenLineage to capture compliance failures. By implementing Data Contracts, organizations can enforce strict data quality standards and track lineage to understand the impact of any discrepancies. This approach not only enhances data reliability but also provides clear visibility into data workflows, facilitating better decision-making and accountability.

  1. Introduce Data Contracts: Explain the concept of Data Contracts and their role as a schema registry to enforce data standards.
  2. Implement Data Quality Checks: Demonstrate how to incorporate data quality checks within Data Contracts to ensure data integrity.
  3. Leverage OpenLineage: Explore the use of OpenLineage for capturing and visualizing data lineage, highlighting the impact of DQ compliance failures.
  4. Practical Applications: Showcase real-world examples and case studies where Data Contracts and OpenLineage have improved data governance and quality.
  5. Future Trends: Discuss the future of data quality management and the evolving role of schema registries and lineage tracking in data ecosystems.
