OpenLineage dbt integration

Wrapper script for automatic metadata collection from dbt

Features

Metadata

  • Model run lifecycle
  • Model inputs / outputs

Requirements

Right now, openlineage-dbt only supports bigquery, snowflake, spark and redshift dbt adapters.

Installation

$ pip3 install openlineage-dbt

To install from source, run:

$ pip install .

Configuration

HTTP Backend Environment Variables

openlineage-dbt uses the OpenLineage client to push data to the OpenLineage backend.

The OpenLineage client depends on environment variables:

  • OPENLINEAGE_URL - point to service which will consume OpenLineage events
  • OPENLINEAGE_API_KEY - set if consumer of OpenLineage events requires Bearer authentication key
  • OPENLINEAGE_NAMESPACE - set if you are using something other than the default namespace for job namespace.

Logging

In addition to conventional logging approaches, the OpenLineage dbt wrapper script provides an alternative way of configuring its logging behavior. By setting the OPENLINEAGE_DBT_LOGGING environment variable, you can establish the logging level for the openlineage.dbt and its child modules.

You can also set log level of dbtol which is deprecated.

Usage

To begin collecting dbt metadata with OpenLineage, replace dbt run with dbt-ol run.

Additional table and column level metadata will be available if catalog.json, a result of running dbt docs generate, will be found in the target directory.

If you need to send events without running the job you can use the command dbt-ol send-events, it will send the metadata of your last run without running the job.
