Airflow is a platform to programmaticaly author, schedule and monitor data pipelines. Use Airflow to author workflows as directed acyclic graphs (DAGs) of tasks. The Airflow scheduler executes your tasks on an array of workers while following the specified dependencies.
.
Furthermore, what is airflow used for?
Apache Airflow is a workflow automation and scheduling system that can be used to author and manage data pipelines. Airflow uses workflows made of directed acyclic graphs (DAGs) of tasks.
Furthermore, how does airflow scheduler work? The Airflow scheduler monitors all tasks and all DAGs, and triggers the task instances whose dependencies have been met. The Airflow scheduler is designed to run as a persistent service in an Airflow production environment. To kick it off, all you need to do is execute airflow scheduler .
Subsequently, one may also ask, when should you not use airflow?
A sampling of examples that Airflow can not satisfy in a first-class way includes: DAGs which need to be run off-schedule or with no schedule at all. DAGs that run concurrently with the same start time. DAGs with complicated branching logic.
How do I check airflow status?
To check the health status of your Airflow instance, you can simply access the endpoint "/health" . It will return a JSON object in which a high-level glance is provided. The status of each component can be either “healthy” or “unhealthy”.
