Openlineage Prefect

Basic Configuration

At a minimum, define a namespace, Prefect API URL and transport consisting of a type, URL and endpoint. All three can be supplied using environment variables.

For example:

export OPENLINEAGE_NAMESPACE='prefect_test' &&
export OPENLINEAGE__TRANSPORT__TYPE='http' &&
export OPENLINEAGE__TRANSPORT__URL='http://lineageconsumer.com:5000' &&
export OPENLINEAGE__TRANSPORT__ENDPOINT='/api/v1/lineage' &&
export PREFECT_API_URL='http://prefecthost.com:4200/api'

For more details about OpenLineage transport options and how to configure them, consult the OpenLineage Python Client Documentation.

Execution

Import the openlineage_prefect package and execute collect_and_process_runs() asynchronously in its own process.

For example:

import asyncio
import openlineage_prefect
from openlineage_prefect.prefect_adapter.listener import PrefectOpenLineageListener

async def main():
    await PrefectOpenLineageListener().collect_and_process_runs()

if __name__ == "__main__":
    asyncio.run(main())

Datasets

The integration looks for datasets in Prefect Artifacts. To attach input and output datasets to job runs, use create_table_artifact() from the Artifact library. Provide a namespace, typically the dataset URI, and name to the adapter via an artifact's table and description, respectively. Distinguish the type of dataset by appending _output or _input to the description.

For example:

ol_table = [{"database_uri":"duckdb:///customers_db", "table":"customers"}]

create_table_artifact(
    key="upstream-insert",
    table=ol_table,
    description="ol-dataset_output"
)
