RabbitMQ备用交换和交换以交换绑定

Question

RabbitMQ v3.7.8

(AE = alternate exchange)

---

The documentation states:

Whenever an exchange with a configured AE cannot route a message to any queue, it publishes the message to the specified AE instead.

It also explains:

If an AE cannot route a message, it in turn publishes the message to its AE, if it has one configured. This process continues until either the message is successfully routed, the end of the chain of AEs is reached, or an AE is encountered which has already attempted to route the message.

I assume any queue means any queue in the chain much in the same way the AE is resolved.

Expect FOO_Alt not to be triggered.

Are my expectations correct?

Answer 1

You should be correct. Of course, the best way to know is to try it out.
