I think this is an identifier for column_keys used in KmsClient to get key
to wrap or unwrap real key that encrypt dataset. In the example, I want to use
same key for column and footer, so i just used FOOTER_KEY_NAME in the dict. Is
there anything i‘m misunderstanding? And I apologize for the confusion I have
caused.
