mik-laj opened a new issue #8187: Extend elastic DAG with a binary tree, grid URL: https://github.com/apache/airflow/issues/8187 **Description** We have ["elastic DAG"](https://github.com/apache/airflow/blob/master/scripts/perf/dags/elastic_dag.py#L77) which we use in various performance tests. It allows you to generate any DAG using environment variables. An example test that uses such a DAG looks like this ```python with mock.patch.dict("os.environ", { "PERF_DAGS_COUNT": str(dag_count), "PERF_TASKS_COUNT": str(task_count), "PERF_START_AGO": start_ago, "PERF_SCHEDULE_INTERVAL": schedule_interval, "PERF_SHAPE": shape, }), conf_vars({ ('scheduler', 'use_job_schedule'): 'True', }): dagbag = DagBag(dag_folder=ELASTIC_DAG_FILE, include_examples=False) with assert_queries_count(expected_query_count): processor = DagFileProcessor([], mock.MagicMock()) processor._process_dags(dagbag.dags.values()) ``` Source: https://github.com/apache/airflow/blob/6bd2e59/tests/jobs/test_scheduler_job.py#L1175 This DAG File allows you to generate DAGs that contain all the tasks connected in a linear manner or have no connections. It would be useful to add more complex DAGs, especially binary trees or/and grids. This will allow us to test more complex cases more easily.  **Use case / motivation** N/A **Related Issues** N/A
