Publish to multiple routing keys

[Rambabu]

Hi,

Is it possible to publish multiple routing keys?

Eg: Consumer A binded with "A"
      Consumer B binded with "B"

     Can i publish message to A and B at a time?

Thanks

It is not possible to publish multiple routing keys in a message, but multiple routing criteria can be included in a single routing key.

In the example stated by you,

Consumer A can bind for #.A.#

Consumer B can bind for #.B.#

In this case, a message published with routing key A.B would get routed to both consumers A & B.

sender selected distribution is what you are looking for.

We use this to route the same message to multiple recipients.

E.g.:

routing_key: "A"

header.CC: "B"

body: "M"

will route message M to both A and B.

Both Sender-Selected Distribution and topic/fanout exchanges are good options.
The downside of the former is that your publisher needs to be hyperaware of the queues.

We use Sender-Selected Distribution with topic exchanges so hyper-awareness of queues is not needed :)
