Airflow version: v1.10.5 What I am looking for is when I run a backfill for multiple dates, then all the tasks in DAG for a specific date should execute first and then the next date and so on. But I am noticing that the first task is running for all dates, then the next task for all dates and so on. So, first dag run is not finishing before the second dag run. Here are the dag parameters that I am using. * max_active_runs=1 Only 1 dag run at a time * concurrency=1 There are multiple branches in the DAG. Want only 1 task to run at a time. * depends_on_past=False for all tasks Please help as I need to run this for more than 2 months and it would be difficult to run for individual dates. Thanks Vishnuraayan
