Dagster Orchestration

Dagster is a modern data orchestration platform for building, testing, and monitoring data pipelines. Unlike Airflow (which treats pipelines as DAGs of tasks), Dagster models pipelines as asset dependencies—named data outputs with clear lineage. Example: Extract data from API → Transform with Pandas → Load to warehouse → Compute metrics → Update dashboard. Dagster tracks each asset, knows which upstream assets changed, and reruns downstream jobs as needed.
