Operators are the main building blocks of Airflow, but operators rely heavily upon Hooks to interact with all of their source and destination systems. Hooks are used as a away to abstract the methods you would use against a source system. Hooks should be used when interacting with any external system. Working with Operators. Airflow provides prebuilt operators for many common tasks. All operators are derived from BaseOperator and acquire much functionality through inheritance.
