Set Message TTL to one hour RabbitMQ

Question

How can I set the message TTL ( Not the Queue ) from either the

Exchange ( The exchange sends to multiple queues )
Message ( when publishing the message )
Queue ( On the queue itself but again this is the Message TTL and not the Queue TTL )

I'm running RabbitMQ 3.x, Symfony 2.1.x and the RabbitMqBundle.

What I've tried:

Setting the Message TTL when I make the queue itself from the RabbitMQ Admin UI

I set the message properties to 'x-message-ttl' => 3600000. In the RabbitMQ config it looks like this:

{
    "name": "blah_queue",
    "vhost": "foobar",
    "durable": true,
    "auto_delete": false,
    "arguments": {
            'x-message-ttl' => 3600000
    }
},

this is the error I get:

PRECONDITION_FAILED - inequivalent arg 'x-message-ttl'for queue

I tried setting in the config.yml ( symfony / https://github.com/videlalvaro/RabbitMqBundle / README )

this gives a bunch of errors with the AMQP library the bundle uses.

I tried modifying the AMQP library itself to allow the x-message-ttl message properties and I get an exception Error sending data.

Has anyone set the Message TTL using the RabbitMQBundle?

queue_options:    {name: 'blah_queue', arguments: {'x-message-ttl' => 3600000}}

I believe you want to do something like this: `arguments: {'x-message-ttl' : ['I', 3600000]}' look at [this test file](https://github.com/romainneutron/php-amqplib/blob/9165f99461c3455ddc93916ad0821e99b0d19c43/demo/queue_arguments.php) for the under lying library — james_t, Jan 16 '13 at 20:58

Sorry that was one of the options I tried already, it didn't work – Phill Pafford Jan 17 '13 at 13:09

This works correctly for me with Rabbit 2.8 and the latest versions of both RabbitMQBundle and php-ampqlib. Haven't test with 3.x releases of Rabbit, but perhaps the option has changed? – james_t Jan 17 '13 at 16:12

Also, you need to delete the queue before running a consumer/producer. You cannot add this argument to a queue which does not already have it. – james_t Jan 17 '13 at 16:14
Tested with RabbitMQ 3.0.1. Works fine. – james_t Jan 17 '13 at 16:18
I hacked it to work at the message level: https://github.com/videlalvaro/RabbitMqBundle/issues/80 – Phill Pafford Jan 17 '13 at 17:46

I can set the queue message time to live from the rabbitmq management console like this:

I'm using RabbitMQ 3.1.5 on Fedora Linux, visit this in the browser:

http://your_rabbitmq_server.com:15672
Click "Queues" tab and scroll down to where it says: "Add a new queue"

Under the subsection: "Add a new queue", fill out these text boxes:

Virtual host:             /
Name:                     myqueue1
Durability:               Durable
Auto delete:              No
Message TTL:     
Auto expire: 
Max length: 
Dead letter exchange:
Dead letter routing key: 

Argument key      = x-message-ttl
Argument value    = 3600000
Argument datatype = number

Click OK to save it.

Now I could consume from the queue and the message will still be there for the specified time.
