Sep 28, 2018 · So it’s traditionally called a DAG, which is a directed acyclic graph. So Airflow provides a way of defining these jobs as a graph and executing them. What makes it desirable is that it controls and it abstracts out a lot of the details, where potentially you want to [inaudible 0:24:16.6] the jobs for network failures.
Airflow DAG(Credit: Apache Airflow). In Airflow all workflows are DAGs. A Dag consists of operators. An operator defines an individual task that needs to be performed.Nov 25, 2020 · Airflow does not support DAGs with loops. After all, the abbreviation DAG stands for Directed Acyclic Graph, so we can’t have cycles. It is also not the standard usage of Airflow, which was built to support daily batch processing. All of that does not stop us from using a simple trick that lets us run a DAG in a loop.

I was exploring the option of ExternalTaskSensor but got confused with execution_delta as I am planning to skip the current runs if previous is still running but I think you made a valid point of setting catchup to True so that there is always a previous run to check on.
