We are trying to use DBT in airflow.  
We create airflow DAGs with different models using incremental materialization.

ex. source → wallet → product  
There are two airflow DAGs  
We wan to know the wallet DAG whether it is finished before dbt run product.

How can I get those information to make cross-DAG dependencies or right execution order.
