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
