>            Reporter: Xiaodong DENG

> We can define connections either in metadata database or environment variables.
>  
> However, how about there are connections with the same conn_id in both metadata database
and environment variables? Will one of them be picked? Which one? Or a random one will be
picked?
>  
> The answer is: Airflow will check environment variables first.[https://github.com/apache/incubator-airflow/blob/master/airflow/hooks/base_hook.py#L70] 
The "random picking" mechanism will only be applicable for multiple connections with the same
conn_id in metadata database (if there is no connection with the same conn_id defined in environment
variables).
>  
> This should be made clear in the documentation.
