Marquez is an open-source metadata service for collecting, aggregating, and visualizing a data ecosystem's metadata. It serves as the reference implementation of the OpenLineage specification, providing a REST API, metadata repository, and web UI for dataset lineage and job run tracking.
Use cases
- track data lineage across pipelines
- visualize dataset dependencies and job graphs
- collect OpenLineage metadata from Airflow, Spark, dbt, and Flink
- audit dataset schema change history
- perform root cause analysis for failed data jobs
- build a data catalog with dataset discovery
- monitor job runtimes and dataset access frequency
When to choose
- you need centralized lineage tracking across multiple orchestration and processing frameworks
- you want an OpenLineage-compatible metadata backend with a visual lineage UI
- you need provenance and schema history for data governance or auditing
- you run heterogeneous data pipelines and need upstream/downstream dependency visibility
When to avoid
- you need a full-featured commercial data catalog with access controls and glossary management
- your stack is a single tool with built-in lineage
- you want a lightweight embedded library rather than a deployed service
- you need column-level lineage out of the box without additional integrations
