#+title: Airflow Tasks
#+filetags: :airflow:database:definitions:
A task in the context of airflow is the basic unit of execution. They are arranged into [[id:3b16e19a-62f0-4705-a451-a8790181941f][Dags]] and then have upstream and downstream dependencies set between them in order to express the order in which they should be run.
There are three kinds of tasks:
1. Operators: they are predefined task templates that you can string together quickly.
2. Sensors: special subclass of operators, which are entirely about waiting for an external event to happen.
3. A Taskflow-decorated @task, which is a custom python function packaged as a task.
