[rabbitmq-discuss] Binding key and routing key

Wed Sep 25 23:33:27 BST 2013

Actually, if you type "binding key" into the search field on the RabbitMQ site, 
you discover that the term is used (in the sense Nikita espouses) in two tutorials,
in the Exchange to Exchange bindings blog entry, and in the discussion on Alternate
Exchanges.

The STOMP adapter page refers to a binding 'pattern', but I didn't find any other
references.

There are phrases like "the binding's routing key" in the rabbitmqctl manual page,
and (interestingly) the Introduction to the AMQP 1.0 Draft (presentation pdf) uses
the term unconsciously on a Topic Exchange diagram.

I think that the term binding key, used consistently, would improve the description
and understanding of bindings no end.  This point seems to have been embraced by
the tutorials quite successfully.
