Cross-Domain Dependencies¶

Models in different domains can depend on each other seamlessly.

Overview¶

dmp-af automatically creates ExternalTaskSensors for cross-DAG dependencies.

How It Works¶

When a model in domain_a references a model in domain_b:

1. dmp-af detects the cross-domain reference
2. Creates an ExternalTaskSensor in domain_a's DAG
3. Waits for domain_b's task to complete
4. Then executes domain_a's model

Example¶

# Domain: svc_orders
models:
  - name: svc_orders.clean_orders
    config:
      schedule: "@daily"

# Domain: dmn_analytics
  - name: dmn_analytics.orders_report
    config:
      schedule: "@daily"
      dependencies:
        svc_orders.clean_orders:
          wait_policy: last
