RabbitMQ and RabbitMQBundle routing keys configuration to multi consumer - rabbitmq

Question

I'm using RabbitMqBundle in Symfomy4.
What i would like to achieve is to publish a message (a notification in my case) and by a routing key choose if to store the message in Db or send it by email or both.
I'm focused on topic exchange but i can't figure out how to reach this goal, maybe i didn't understand completely the mechanism of RabbitMQ, but i'm completely new to it.
This is my configuration
old_sound_rabbit_mq:
connections:
default:
#url: '%env(RABBITMQ_URL)%'
url: 'amqp://guest:guest#localhost:5672'
vhost: '/'
lazy: false
connection_timeout: 3
read_write_timeout: 3
producers:
notifications:
connection: default
exchange_options: {name: 'notifications', type: topic}
consumers:
store_notifications:
connection: default
exchange_options: {name: 'notifications', type: topic}
queue_options:
name: 'notifications'
routing_keys:
- 'notification.store'
# - 'notification.*' # this will match everything
callback: App\Consumer\Notification\DbHandler
email_notifications:
connection: default
exchange_options: {name: 'notifications', type: topic}
queue_options:
name: 'notifications'
routing_keys:
- 'notification.email'
callback: App\Consumer\Notification\EmailHandler
In this case i can publish a message just to one of the routing key: notification.store or notification.email
I would like to have something like publish($msg, ['notification.store', 'notification.email']), but i know i can make a consumer listen to multiple routing keys and with wildcard but i can't figure out how to configure it.
Is this possible?

Answer 1

I think you can do by:
If you just want to store DB, the routing key is: notification.store
If you just want to send email, the routing key is: notification.email
If you want to do both, the routing key is: notification.both
Then, your queue should bound to the exchange with these routing keys:
store_notifications: [notification.store, notification.both]
email_notifications: [notification.email, notification.both]
By doing this, if the message with routing notification.store just go to store_notifications, notification.email just go to email_notifications. But message with routing notification.both goes to both queues.
Configuration:
consumers:
store_notifications:
connection: default
exchange_options: {name: 'notifications', type: topic}
queue_options:
name: 'notifications'
routing_keys:
- 'notification.store'
- 'notification.both'
callback: App\Consumer\Notification\DbHandler
email_notifications:
connection: default
exchange_options: {name: 'notifications', type: topic}
queue_options:
name: 'notifications'
routing_keys:
- 'notification.email'
- 'notification.both'
callback: App\Consumer\Notification\EmailHandler
Hope this helps.
