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.

When referencing the connection in the Airflow pipeline, the conn_id should be the name of the variable without the prefix. For example, if the conn_id is named postgres_master the environment variable should be named AIRFLOW_CONN_POSTGRES_MASTER (note that the environment variable must be all uppercase).
