Multiple routing keys

[Adam Curtis]

Hey guys! It would be really handy if we could specify multiple routing keys 👍

Hi, would have time to make a PR for it? According to RabbitMQ docs, this could be achieved like this:

for severity in severities:
    channel.queue_bind(exchange='direct_logs',
                       queue=queue_name,
                       routing_key=severity)

(https://www.rabbitmq.com/tutorials/tutorial-four-python.html).
So in the code, apart from switching from string to list in routing key, you would have to iterate over the list in this method: https://github.com/AirHelp/rabbit-amazon-forwarder/blob/master/rabbitmq/consumer.go#L109. I can write some tests for that piece of code :)

Yeah, it should be as simple as adding a few extra queue binds in a loop like you've mentioned.

I guess the next thing to consider is how do we specify in the mapping file? At the moment routing is a string. Changing that to an array will obviously be a breaking change. Do we add a new option or make a breaking change?

[Adam Curtis]

I guess we could make RoutingKey a generic interface{} and check if its a string or []string as a possible solution?

[Filip Haftek]

Breaking change is not possible at the moment, as this is used on production. routingKeys could be added as an extra filed to json imho.

Makes sense! I'll have a stab at this sometime 👍
