Airflow will use the directory set in the environment variable AIRFLOW_HOME to store its configuration and our SQlite database. This directory will be used after your first Airflow command. If you don't set the environment variable AIRFLOW_HOME, Airflow will create the directory ~/airflow/ to put its files in.

After that, whenever you restart Airflow services, the DAG will retain its state (paused or unpaused). So if you restart Airflow, the scheduler will check to see if any DAG Runs have been missed based off the last time it ran and the current time and trigger DAG Runs as needed.

How a Mass Airflow Sensor Works Mass Air Flow Sensor Diagram . The sensor pictured on the right, converts air flowing past a heat sensing element into an electrical signal. They use this as an input signal to the vehicle’s main computer.

Scheduling & Triggers¶. The Airflow scheduler monitors all tasks and all DAGs, and triggers the task instances whose dependencies have been met. Behind the scenes, it spins up a subprocess, which monitors and stays in sync with a folder for all DAG objects it may contain, and periodically (every minute or so) collects DAG parsing results and inspects active tasks to see whether they can be ...
