Define a Teradata connection in Environment Variable

Airflow connections may be defined in environment variables in either of one below formats.

1. JSON format

2. URI format

   Note

   The naming convention is AIRFLOW_CONN_CONN_ID, all uppercase (note the single underscores surrounding CONN). So if your connection id is teradata_conn_id then the variable name should be AIRFLOW_CONN_TERADATA_CONN_ID
