The news

Why enterprises add Dagster  to Databricks

Cross-workspace orchestration

Databricks Workflows operates within one workspace; Dagster spans all of them.

Full-stack lineage

Dagster tracks assets across modern data platforms, filling the gaps Unity Catalog's lineage doesn't cover.

Multi-team governance

RBAC, ownership, freshness SLAs, and quality gates enforced across teams and workspaces.

The promise

Dagster stays Dagster

Dagster continues as a supported product. Dagster keeps its name and open source license, and Dagster+ continues as a supported commercial offering.

“Prefect is the right home for Dagster. Asset orientation matters more every year as data becomes the foundation for AI, and this gives our product, our customers, and our community a stronger place to keep building.”

Pete Hunt

CEO | Dagster Labs
