4.7.6. Exclusive Bindings for Direct Exchanges
Declaring an exclusive binding on a direct exchange ensures that a maximum of one consumer is bound to the exchange using this key at any time. When a new consumer is subscribed to the exchange using this key, the previous consumer's binding is dropped synchronously. This allows messaging routing to be switched between consumers with guaranteed message atomicity, with no possibility of dropped messages or duplicate delivery while the composite bind/unbind operation is taking place.
The exchange-bind argument
qpid.exclusive-binding is used to declare an exclusive binding.
drain -f "amq.direct; {create:always, link: {name:one, x-bindings:[{key:unique, arguments: {qpid.exclusive-binding:True}}]}}"
Note that exclusive bindings are not available over AMQP 1.0.
