Overview

OpenLineage is an Open standard for metadata and lineage collection designed to instrument jobs as they are running. It defines a generic model of run, job, and dataset entities identified using consistent naming strategies. The core lineage model is extensible by defining specific facets to enrich those entities.

Status

OpenLineage is an LF AI & Data Foundation incubation project under active development, and we'd love your help!

Problem

Before

• Duplication of effort: each project has to instrument all jobs
• Integrations are external and can break with new versions

With OpenLineage

• Effort of integration is shared
• Integration can be pushed in each project: no need to play catch up

Scope

OpenLineage defines the metadata for running jobs and the corresponding events. A configurable backend allows the user to choose what protocol to send the events to.

Core model

A facet is an atomic piece of metadata attached to one of the core entities. See the spec for more details.

Spec

The specification is defined using OpenAPI and allows extension through custom facets.

Integration matrix

The OpenLineage repository contains integrations with several systems.

Name	Table-level lineage	Column-level lineage
Apache Spark	✅	✅1
Apache Airflow	✅	✅2
Dagster	✅	❌
dbt	✅	❌
Flink	✅	❌

1. Does not support SELECT * queries with JDBC.
2. Supports SQL-based operators other than BigQuery.
