If you do nothing, the OpenLineage backend will receive the Job and the Run from your DAGs, but, MARQUEZ_URL=Įxtractors : Sending the correct data from your DAGs MARQUEZ_URL, MARQUEZ_NAMESPACE and MARQUEZ_API_KEY variables.
AIRFLOW DOCKER REQUIREMENTS.TXT CODE
OPENLINEAGE_AIRFLOW_DISABLE_SOURCE_CODE - set to False if you want the source code of callables provided in the PythonOperator to be sent in OpenLineage events.įor backwards compatibility, openlineage-airflow also supports configuration via.OPENLINEAGE_NAMESPACE - set if you are using something other than the default namespace for the job namespace.OPENLINEAGE_API_KEY - set if the consumer of OpenLineage events requires a Bearer authentication key.OPENLINEAGE_URL - point to the service that will consume OpenLineage events.The OpenLineage client depends on environment variables: Openlineage-airflow uses the OpenLineage client to push data to OpenLineage backend. On DAG complete, also mark the task as complete in OpenLineageĬonfiguration HTTP Backend Environment Variables.Collect task run-level metadata (execution time, state, parameters, etc.).Collect task input / output metadata ( source, schema, etc.).On DAG start, collect metadata for each task using an Extractor if it exists for a given operator.The OpenLineageBackend does not take into account manually configured inlets and outlets. In contrast to integration via subclassing a DAG, a LineageBackend-based approach collects all metadata Set your LineageBackend in your airflow.cfg or via environmental variable AIRFLOW_LINEAGE_BACKEND to openlineage.lineage_backend.OpenLineageBackend This method has limited support: it does not support tracking failed jobs, and job starts are registered only when a job ends. This means you don't have to do anything besides configuring it, which is described in the Configuration section. The integration automatically registers itself for Airflow 2.3 if it's installed on the Airflow worker's Python.
AIRFLOW DOCKER REQUIREMENTS.TXT INSTALL
To install from source, run: $ python3 setup.py install Note: You can also add openlineage-airflow to your requirements.txt for Airflow. Installation $ pip3 install openlineage-airflow It's more modular and reusable to keep it separate than embed it inside a Dockerfile.A library that integrates Airflow DAGs with OpenLineage for automatic metadata collection. Hopefully this makes it clearer that requirements.txt declares required packages and usually the package versions. Presumably other modern IDEs do the same, but if you're developing in plain text editors, you can still run a script like this to check the installed packages (this is also handy in a git post-checkout hook):Įcho -e "\nRequirements diff (requirements.txt vs current pips):"ĭiff -ignore-case /dev/null | sort -ignore-case) -yB -suppress-common-lines.P圜harm will look for a requirements.txt file, let you know if your currently installed packages don't match that specification, help you fix that, show you if updated packages are available, and help you update.To "freeze" on specific versions of the packages to make builds more repeatable, pip freeze will create (or augment) that requirements.txt file for you.You won't have to copy/paste the list of packages. To manually install those packages, inside or outside a Docker Container, or to test that it works without building a new Docker Image, do pip install -r requirements.txt.First consider going with the flow of the tools:
