'Composer Airflow - Cross DAG Task Dependancy
I have below 2 DAGs and tasks
DAGA - Task1,Task2,Task3
DAGB - Task4,Task5,Task6
Now Task4 & 5 of DAG B depends on Task1 of DAGA and Task6 depends on Task3 but I want this dependency only on Monday and for remaining days I don't want this dependency.
Solution 1:[1]
For this kind of cross dag dependency wherein you want certain tasks of a dag to run on a particular day of the week , use TriggerDagRunOperator along with BranchPythonOperator. This operator function must return a list of task IDs that the DAG should proceed with based on some logic.
