    var element = {};
    for (var key in event.queryStringParameters) {
            element[key] = event.queryStringParameters[key];
    }

Understanding RabbitMQ

Introduction RabbitMQ is a centralized message broker based on the AMQP (Advanced Message Queuing Protocol) protocol, acting as a Middleware between Producers and Consumers of different systems. In a message system, Publishers sends a message to a message broker where messages are consumed some time later by one or more Subscribers. By introducing a message brokeer between systems we are decoupling the sender application from the receiver.

With a message system you send a message to a message broker first and when the consumers or listeners of it become online they can start consuming from the message queue. This means you can keep sending messages without even care if the other application is online or if they had any failures. RabbitMQ Architecture Exchange, queue and bindings are the ...
