RabbitMQ is perfect for this situation. You have a number of options to do what you want. I suggest reading the documentation to get a better understanding. I would suggest that you use a topic or direct exchange. Topic is more flexible. It goes like this. Producer code connects to the RabbitMQ Broker and creates … Read more
Modern versions of RabbitMQ have a delivery acknowledgement timeout: In modern RabbitMQ versions, a timeout is enforced on consumer delivery acknowledgement. This helps detect buggy (stuck) consumers that never acknowledge deliveries. Such consumers can affect node’s on disk data compaction and potentially drive nodes out of disk space. If a consumer does not ack its … Read more

There are several types of exchanges. The fanout exchange ignores the routing key and sends messages to all queues. But pretty much all other exchange types use the routing key to determine which queue, if any, will receive a message. The tutorials on the RabbitMQ website describes several usecases where different exchange types are useful … Read more
Make sure you call sudo rabbitmqctl stop_app before issuing the cluster command. That seemed to be the problem for me. Then make sure you call sudo rabbitmqctl start_app to begin it again 🙂
Ready Is the number of messages that are available to be delivered. Unacknowledged Is the number of messages for which the server is waiting for acknowledgement(If a client recieved the message but dont send a acknowledge yet). Total Is the sum of Ready and Unacknowledged messages. About your second question: Publish This is the rate … Read more
There are no x-message-ttl argument set by default from the broker side, so basically you can interpret default value as infinity. If you publish message without ttl to queue without ttl set (yupp, there are per-message and per-queue ttl arguments, see note below): if message published as persistent and queue declared as persistent message will … Read more
A consumer, by default will read as many messages as the bandwidth can handle regardless of actual message processing time by the consumer. You need to set prefetch values by modifying the Quality of Service (QoS) of the channel to restrict how many messages it will try to pick up at one time. Check out … Read more
I faced the same problem and my investigations led me to https://stackoverflow.com/a/34538688 which helped me solve it. After following the steps in that answer, start the service and the problem should be solved. Basically, the problem is caused by the RabbitMQ installer not registering the service correctly.
An overview – A protocol – A set of rules. AMQP – AMQP is an open internet protocol for reliably sending and receiving messages. MOM (message-oriented-middleware) – is an approach, an architecture for distributed system i.e. a middle layer for the whole distributed system, where there’s lot of internal communication (a component is querying data, … Read more
