Ruby amqp updating client properties

With the complexity presented in enterprise scenarios a service oriented architecture (SOA) where multiple applications communicate with each other lends itself quite well.This post uses a case study to showcase how a message-oriented middleware with Advanced Messaging Queuing Protocol (AMQP) can enhance a Representational State Transfer (REST) architecture and enable asynchronous communication.The Sensu Plugins project currently maintains of plugins providing various checks, handlers, and mutators which are used by thousands of organizations around the world.Most of the plugins maintained by the Sensu Plugins project are Ruby-based plugins which are distributed via (and installable via ).

Plain Credentials(username, password) connection = pika. The first thing we need to do is to establish a connection with Robo MQ broker.This is a two-way message communication also using direct exchange but unlike the RPC pattern, the reply queue is bound to an exchange allowing more than one client to subscribe to and process the replies asynchronously.In addition any service application can process a request from any client. Connection Parameters(host = server, port = port, virtual_host = vhost, credentials = credentials, heartbeat_interval = 60)) channel = connection.channel() channel.queue_declare(queue = reply Queue, exclusive = True, auto_delete = True) channel.queue_bind(exchange = exchange Name, queue = reply Queue, routing_key = reply Key) channel.basic_consume(consumer_callback = on Message, queue = reply Queue, no_ack = True) channel.start_consuming() After that producer can publish messages to the exchange through routing key of the request Queue on consumer side. Basic Properties(content_type = "text/plain", delivery_mode = 1, reply_to = reply Key) channel.basic_publish(exchange = exchange Name, routing_key = request Key, body = "Hello World!A proposed solution would have to adhere to the following constraints: A central pub-sub mechanism would suffice the first two constraints.

Client apps would be able to subscribe to certain types of updates without the master data apps needing to know which apps are subscribed.

As a junior developer it was a great opportunity to work with two excellent tools for background jobs: Rabbit MQ and
