Data Lineage

CircleCI codecov PyPI image image

Tokern Lineage Engine is a fast and easy to use platform to collect, visualize and analyze column-level data lineage in databases, data warehouses and data lakes in AWS and GCP.

Tokern Lineage Engine helps you browse column-level data lineage

Utilize column-level lineage to add rich context and powerful automation for common data management tasks like:

  • Track and debug data quality.
  • Track PII, PHI and other sensitive data and their access rights.
  • Save costs by removing unused ETL pipelines and datasets.
  • Enrich your data dictionary to help users find the right dataset for their analysis.

Check out the post on using data lineage for cost control as an example.
