For historical reasons, configuring HTTPS connectivity via HTTP operator is, well, difficult and counter-intuitive. The Operator defaults to http protocol and you can change the schema used by the operator via scheme connection attribute. DAGs. A DAG (Directed Acyclic Graph) is the core concept of Airflow, collecting Tasks together, organized with dependencies and relationships to say how they should run. It defines four Tasks - A, B, C, and D - and dictates the order in which they have to run, and which tasks depend on what others. For DAG-level permissions exclusively, access can be controlled at the level of all DAGs or individual DAG objects. This includes DAGs.can_read, DAGs.can_edit, and DAGs.can_delete.
