Agenda:

Welcome to messaging

Why messaging ?

  • Get data from point A to point B 
  • Decouple publishers and consumers
  • Queueing for later delivery
  • Asynchronous
  • Load balancing and scalability

 MQTT, AMQP and STOMP

TCP/IP-based

 MQTT

Message Queue Telemetry Transport

  • Open : created by IBM & Eurotech and donated to Eclipse “Paho” M2M project (OASIS standard in 2014)
  • Lightweight : smallest packet size 2 bytes (header), reduced clients footprint (C# M2Mqtt library 30 KB)
  • Reliable : three QoS and patterns to avoid packet loss on client disconnection
  • Simple :
    • TCP based
    • Asynchronous
    • Publish/Subscribe
    • Few verbs
    • Payload agnostic

 AMQP

Advanced Message Queuing Protocol

  • Internet protocol - like HTTP, TCP - but ASYNCHRONOUS
  • Routing (where to send messages)
  • Delivery (how to get there)
  • Fidelity (what goes in must come out)
  • Wide range of features:
    •  queuing
    • topic-based publish-and-subscribe messaging
    • flexible routing
    • transactions
    • security

Standard port: 5672

 AMQP

Advanced Message Queuing Protocol

STOMP

Simple/Streaming Text Oriented Messaging Protocol

  •  text-based
  • more analogous to HTTP
  • possible to connect to a STOMP broker using something as simple as a telnet client
  • destination (instead of queue)
  • simple and lightweight (for humans)

STOMP

Simple/Streaming Text Oriented Messaging Protocol

MESSAGE
subscription:0
message-id:007
destination:/queue/a
content-type:text/plain

hello queue a^@
SUBSCRIBE
id:0
destination:/queue/foo
ack:client

RabbitMQ: The Polyglot Broker

RabbitMQ - Messaging that just works

RabbitMQ

  • RabbitMQ is an AMQP messaging broker written in Erlang
  • RabbitMQ 3.0 supports MQTT, AMQP and STOMP
  • Core development team in London, UK
  • Rabbit is a part of AMQP Working Group

Virtual Hosts

  • Created for administrative purposes
  • Access control
  • Each connection (and all channels inside) must be associated with a single virtual host
  • Each virtual host comprises its own name space, a set of exchanges, message queues and all associated objects 

 

Hello World

 

 $ python send.py
 [x] Sent 'Hello World!'


 $ python receive.py
 [*] Waiting for messages. To exit press CTRL+C
 [x] Received 'Hello World!

Queue

  • named "weak FIFO" buffer
     
  • FIFO is guaranteed only with 1 consumer
     
  • Can be durable, temporary (private to 1 consumer) or auto-deleted
     
  • A message routed to a queue is never sent to more than one client unless it is being resent after failure or rejection
     
  • You can get server to auto generate and assign queue name for your queue — this is usually done for private queues 

Messages

  • Messages carry content (header + body)
     
  • Content body is opaque block of binary data
     
  • Broker never modifies content body
     
  • AMQP defines several "content classes," each with specific syntax (which headers can be used) and semantics (which methods are available for such messages) 

 

Workers

distribute time-consuming tasks among multiple workers

Round-robin dispatching

$ python new_task.py First message.
$ python new_task.py Second message..
$ python new_task.py Third message...
$ python new_task.py Fourth message....
$ python new_task.py Fifth message.....
// shell 1
$ python worker.py
 [*] Waiting for messages. To exit press CTRL+C
 [x] Received 'First message.'
 [x] Received 'Third message...'
 [x] Received 'Fifth message.....'

// shell 2
$ python worker.py
 [*] Waiting for messages. To exit press CTRL+C
 [x] Received 'Second message..'
 [x] Received 'Fourth message....'

Workers

  • Message acknowledgment

     
  • Forgotten acknowledgment
     

 

  • Message durability
$ sudo rabbitmqctl list_queues name messages_ready messages_unacknowledged
Listing queues ...
hello    0       0
...done.
channel.queue_declare(queue='hello', durable=True)

channel.basic_publish(exchange='',
      routing_key="task_queue",
      body=message,
      properties=pika.BasicProperties(
         delivery_mode = 2, # make message persistent
      ))
channel.basic_consume(callback,
                      queue='hello',
                      no_ack=True)

Workers

  • Fair dispatch
     
  • RabbitMQ doesn't allow you to redefine an existing queue with different parameters
channel.basic_qos(prefetch_count=1)

Workers

  • Marking messages as persistent doesn't fully guarantee that a message won't be lost. 
    • Transactions: x 250 slower !!!
    • Confirm mode

       
    •  
  • Queue Length Limit
$conn = new AMQPConnection('192.168.1.1', 5672, 'user', 'pass');
$ch = $conn->channel();
$ch->set_ack_handler(function($message){});
$ch->set_nack_handler(function($message){});
$ch->confirm_select();
$ch->wait_for_pending_acks();
$conn = new AMQPConnection('192.168.1.1', 5672, 'user', 'pass');
$ch = $conn->channel();
$arguments = [,
    "x-max-length" => 10000,
    "x-max-length-bytes" => 102400000,
];
$ch->queue_declare(
    $name, $passive, $durable, $exclusive, 
    $autoDelete, $nowait, new AMQPTable($arguments)
);

Publish/Subscribe

  • Exchanges *(default exchange)
    •  direct, topic, headers, fanout
  • Bindings
<?php

list($queue_name, ,) = $channel->queue_declare("");

$channel->queue_bind($queue_name, 'logs');

Publish/Subscribe

sudo rabbitmqctl list_exchanges
Listing exchanges ...

amq.direct	direct
amq.fanout	fanout
amq.headers	headers
amq.match	headers
amq.rabbitmq.log	topic
amq.rabbitmq.trace	topic
amq.topic	topic
bench_exchange	direct
router	direct
someExchange	fanout

$ sudo rabbitmqctl list_bindings
Listing bindings ...
logs    exchange        amq.gen-JzTY20BRgKO-HjmUJj0wLg  queue           []
logs    exchange        amq.gen-vso0PVvyiRIL2WoV3i48Yg  queue           []
...done.

Exchanges

  • A message routing agent
  • Can be durable — lasts till explicitly deleted
  • Can be temporary — lasts till server shuts down
  • Can be auto-deleted — lasts till no longer used
  • There are several types of exchanges, each implements a particular algorithm
  • Each message is delivered to each qualifying queue
  • "Binding" - a link between queue and exchange 

 

Routing

  • Routing key
  • Direct exchange
  • Multiple bindings
$binding_key = 'black';

$channel->queue_bind($queue_name, $exchange_name, $binding_key);

$channel->basic_publish($msg, $exchange_name, $binding_key);

Fanout Exchange

  • routes messages to all of the queues that are bound to it
  • copy of the message is delivered to all N queues

When to use ?

  • MMO games
  • sport news
  • group chats

Fanout Exchange

conn.start
ch   = conn.create_channel
x    = ch.fanout("examples.pings")

10.times do |i|
  q = ch.queue("", :auto_delete => true).bind(x)
  q.subscribe do |delivery_info, properties, payload|
    puts "[consumer] #{q.name} received a message: #{payload}"
  end
end

x.publish("Ping")
[consumer] amq.gen-A8z-tj-n_0U39GdPGncV-A received a message: Ping
[consumer] amq.gen-jht-OtRwdD8LuHMxrA5SNQ received a message: Ping
[consumer] amq.gen-LQTh8IdojOCrvOnEuFog8w received a message: Ping
[consumer] amq.gen-PV-Dg8_gSvLO9eK6le6wwQ received a message: Ping
[consumer] amq.gen-ofAMc3FXRZIj3O55fXDSwA received a message: Ping
[consumer] amq.gen-TXJiZEjwZ0squ12_Z9mP0A received a message: Ping
[consumer] amq.gen-XQjh2xrC9khbMZMg_0Zzfw received a message: Ping
[consumer] amq.gen-XVSKsdWwhyxRiJn-jAFEGg received a message: Ping
[consumer] amq.gen-ZaY2pD_9NaOICxAMWPoIYw received a message: Ping
[consumer] amq.gen-oElfvP_crgASWkk6EhrJLA received a message: Ping

Direct Exchange

  • delivers messages to queues based on the message routing key

used to distribute tasks between multiple workers in a round robin manner

Direct Exchange

conn.start

ch   = conn.create_channel
x    = ch.direct("examples.imaging")

q1 = ch.queue("", :auto_delete => true).bind(x, :routing_key => "resize")
q1.subscribe do |delivery_info, properties, payload|
  puts "[consumer] #{q1.name} received a 'resize' message"
end

q2 = ch.queue("", :auto_delete => true).bind(x, :routing_key => "watermark")
q2.subscribe do |delivery_info, properties, payload|
  puts "[consumer] #{q2.name} received a 'watermark' message"
end

Headers Exchange

conn.start

ch   = conn.create_channel
x    = ch.headers("headers")

q1   = ch.queue("").bind(x, :arguments => 
    {"os" => "linux", "cores" => 8, "x-match" => "all"})

q2   = ch.queue("").bind(x, :arguments => 
    {"os" => "osx",   "cores" => 4, "x-match" => "any"})

q3   = ch.queue("").bind(x, :arguments => 
    {"os" => "windows"})

Routing on multiple attributes that are more easily expressed as message headers than a routing key

Topic Exchange

Route messages to one or many queues based on matching between a message routing key and the pattern that was used to bind a queue to an exchange

Topic Exchange

x    = ch.topic("weathr", :auto_delete => true)

q = ch.queue("americas.south", :auto_delete => true)
    .bind(x, :routing_key => "americas.south.#")

q.subscribe do |delivery_info, properties, payload|
  puts "An update for South America: #{payload}, r
    outing key is #{delivery_info.routing_key}"
end
americas.south.# match:

americas.south
americas.south.brazil
americas.south.brazil.saopaolo
americas.south.chile.santiago

RPC

Remote procedure call

  • RPC over RabbitMQ is easy
  • Client send request message
  • Server replies response message
  • correlation_id

RPC - Server

$channel->queue_declare('rpc_queue', false, false, false, false);

function fib($n) {
    if ($n == 0)
        return 0;
    if ($n == 1)
        return 1;
    return fib($n-1) + fib($n-2);
}

echo " [x] Awaiting RPC requests\n";
$callback = function($req) {
    $n = intval($req->body);
    echo " [.] fib(", $n, ")\n";

    $msg = new AMQPMessage(
        (string) fib($n),
        array('correlation_id' => $req->get('correlation_id'))
        );

    $req->delivery_info['channel']->basic_publish(
        $msg, '', $req->get('reply_to'));
    $req->delivery_info['channel']->basic_ack(
        $req->delivery_info['delivery_tag']);
};

$channel->basic_qos(null, 1, null);
$channel->basic_consume('rpc_queue', '', false, false, false, false, $callback);

RPC - Client

class FibonacciRpcClient {
    /* attributes */

    public function __construct() {
        $this->connection = new AMQPStreamConnection(
            'localhost', 5672, 'guest', 'guest');
        $this->channel = $this->connection->channel();
        list($this->callback_queue, ,) = $this->channel->queue_declare(
            "", false, false, true, false);
        $this->channel->basic_consume(
            $this->callback_queue, '', false, false, false, false,
            array($this, 'on_response'));
    }
    public function on_response($rep) {
        if($rep->get('correlation_id') == $this->corr_id) {
            $this->response = $rep->body;
        }
    }

    public function call($n) {
        $this->response = null;
        $this->corr_id = uniqid();

        $msg = new AMQPMessage(
            (string) $n,
            array('correlation_id' => $this->corr_id,
                  'reply_to' => $this->callback_queue)
            );
        $this->channel->basic_publish($msg, '', 'rpc_queue');
        while(!$this->response) {
            $this->channel->wait();
        }
        return intval($this->response);
    }
};
