airflow backfilling dag run dependancy

Question

When i backfill a dag for specific dates, i want to run it by sequentially, ie i want it to be run day by day

completing all the tasks for the specific day and then next day so on.. I have used the depends_on_past argument, but it is only helping me to set the dependency on tasks not in dag runs.

example :- Dag_A have 4 tasks , i use back fill with depends_on_past, After executing first task in Dag_A (first day) it triggers first task of Dag_A (second day), I dont want it

Answer 1

There is an option to set maximum number of runs per dag in the global airflow.cfg file. The parameter to set is max_active_runs_per_dag.
