Tokern Lineage Engine is fast and easy to use application to collect, visualize and analyze column-level data lineage in databases, data warehouses and data lakes in AWS and GCP.
Tokern Lineage helps you browse column-level data lineage
- visually using kedro-viz
- analyze lineage graphs programmatically using the powerful networkx graph library
Resources
- Demo of Tokern Lineage App
- Checkout an example data lineage notebook.
- Check out the post on using data lineage for cost control for an example of how data lineage can be used in production.
Quick Start

Run docker-compose
docker-compose up -d
If you want to use an external Postgres database, change the following parameters in tokern-lineage-engine.yml:
- CATALOG_HOST
- CATALOG_USER
- CATALOG_PASSWORD
- CATALOG_DB
You can also override default values using environement variables.
CATALOG_HOST=... CATALOG_USER=... CATALOG_PASSWORD=... CATALOG_DB=... docker-compose -f ... up -d
For more advanced usage of environment variables with docker-compose, refer to docker-compose docs
Pro-tip
If you want to connect to a database in the host machine, set
CATALOG_HOST: host.docker.internal # For mac or windows
#OR
CATALOG_HOST: 172.17.0.1 # Linux
