In the previous article RABBITMQ Message Queuing (v): Routing message routing, we implemented a simple log system. Consumer can listen for logs of different severity. However, this is why it is called a simple log system, because it is only able to be set through severity. More standards are not supported. For example syslog UNIX log utility, it can pass severity (Info/warn/crit ...) and module (Auth/cron/kern ...). This is probably what we want: we c

Work QueuesIn the first tutorial we wrote programs to send and receive messages from a named queue. In this one we'll create a work Queue that'll be used to distribute time-consuming tasks among multiple wor Kers.The main idea behind work Queues (AKA: task Queues) was to avoid doing a resource-intensive Task immediately a ND has to-wait for it to complete. Instead We schedule the task to is done later. We encapsulate a task as a message and send it to the queue. A worker process running in the b
