Setting Time-To-Live and Expiration for RabbitMQ Queue in Ballerina Using RabbitMQ Client

Question

I need to set Time-To-Live (TTL) and expiration for a RabbitMQ queue. I am using the RabbitMQ client in Ballerina to interact with RabbitMQ. However, I couldn't find clear documentation or examples of how to achieve this. Are there any specific ways in the Ballerina RabbitMQ client that I should be using for this purpose?

You can use the arguments field of the RabbitMQ QueueConfig to provide any additional configurations (apart from the standard configs defined in the same record) when declaring a queue.

Here's a complete code sample which demonstrates the aforementioned approach.

import ballerinax/rabbitmq;

public function main() returns error? {

    // Create a RabbitMQ client
    rabbitmq:Client newClient = check new ("localhost", 8080);

    // Define the additional arguments as a map of JSON
    map<json> arguments = {
        "x-message-ttl": 60000,
        "x-expires": 800000
    };

    // Declare a RabbitMQ queue with the specified arguments
    check newClient->queueDeclare("demo", {arguments});

    // Close the RabbitMQ client
    check newClient->close();
}
