•MQ support for MQ Light (beta)

IBM Messaging

What is MQ Light?
1. A new messaging API
2. A messaging runtime for on-premise development
and deployment
3. A PaaS messaging runtime for admin-free cloud
deployment (MQ Light Service in Bluemix)
More on all of these throughout the slides...

MQ Light : Software and Cloud
 Messaging that application developers
will love to use, helping them make
responsive applications that scale easily
 3 ways to get it:
Bluemix service
MQ Light software download
Statement of Direction for support in MQ Version
8.
 Open APIs crafted to feel natural in a
growing range of popular languages
 Tooling that makes modular app
development easy

“MQ Light”

MQ Light API - Language support
• Simple, programming Language neutral messaging model
• Idiomatic language & framework API Mappings
• Frictionless development
• Open wire protocol
(AMQP 1.0) &
• Open Source client libraries
• Facilitates community drivers for languages & frameworks

MQ Light Messaging Model – Send Messages
Applications send messages to a topic.
A topic is an address in the topic space
either flat or arranged hierarchically.
1. Send (‘/test/a’, “Hello”);
2. Send (‘/test/a’, “World!”);
Topic Address Space
Sender application

MQ Light Messaging Model – Simple Receive
• Applications receive messages by creating a destination with a pattern
which matches the topics they are interested in.
• Pattern matching scheme based on WMQ.
1. Hello
2. World!
Topic Address Space
Sender application
DESTINATION
Pattern=/test/a

MQ Light Messaging Model – Pub/Sub
• Multiple destinations can be created which match the same topic
• Pub/Sub style.
DESTINATION
1. Hello
2. World!
1. Hello
2. World!
Topic Address Space
Sender application
DESTINATION
Pattern=/test/a
Pattern=/test/#
Client 1
Client 2

MQ Light Messaging Model – Persistent destinations
• Destinations persist for a defined “time to live” after receiver detaches.
Topic Address Space
Sender application
Hello
World!
DESTINATION
Pattern=/test/a
Disconnected client

MQ Light Messaging Model – Sharing
• Clients attaching to the same topic pattern and share name attach to
the same shared destination.
DESTINATION1. Send (‘/test/a’, “Hello”);
1. Hello
2. World!
1. Hello
2. World!
SHARING
Topic Address Space
Sender application
DESTINATION
Pattern=/test/#
Pattern=/test/#
Share=myshare
Client 1
Client 2
Client 3

MQ Light Messaging Model – Client takeover
Hello
Topic Address Space
Sender application
DESTINATION
Pattern=/test/#
Client 1
World!
Client 1
• Applications connect to MQ Light service specify (optional) client ID.
• Re-using the same client ID pre-empts the original connection.
• Ideal for worker takeover in the cloud.

MQ Light Node.JS API
 Installable from NPM
 Fully non blocking – Node.JS style
 Fluent programming style - wrappable into promises.
 Focussed on code simplicity.
 Client seamlessly retries across cloud endpoints
# Receive:
var mqlight = require('mqlight');
var recvClient = mqlight.createClient({service: 'amqp://localhost'});
recvClient.on('started', function() {
recvClient.subscribe('news/technology');
recvClient.on('message', function(data, delivery) {
console.log(data);
});
});
# Send:
var sendClient = mqlight.createClient({service: 'amqp://localhost'});
sendClient.on('started', function() {
sendClient.send('news/technology', 'Hello World!');
});
# Receive:
var recvClient = mqlight.createClient({service: 'amqp://localhost'});
recvClient.on('started', function() {
recvClient.subscribe('news/technology');
recvClient.on('message', function(data, delivery) {
console.log(data);
});
});
# Send:
var sendClient = mqlight.createClient({service: 'amqp://localhost'});
sendClient.on('started', function() {
sendClient.send('news/technology', 'Hello World!');
});

MQ Light Ruby API (Beta)
 Installable from rubygems.org
 Synchronous/blocking client.
 Bluemix connection support
 Backlog
 Auto reconnect.
 Asynchronous non blocking
 TLS
# Receive:
require 'mqlight'
client = Mqlight::BlockingClient.new('amqp://localhost')
client.subscribe('news/technology')
delivery = client.receive('news/technology')
puts delivery.data
# Send:
require 'mqlight'
client.send('news/technology', 'Hello World!')
# Receive:
require 'mqlight'
puts delivery.data
# Send:
require 'mqlight'

MQ Light Python API (Beta)

Introduction to MQ Light Service

Bluemix UI identical to standalone MQ Light UI...

Applications are bound to the services they require
IBM Bluemix – Deployment Options
This is the dashboard for one of
my applications. It’s bound to an
MQ Light service I previously
created
cf create-service mqlight standard “MQ Light-7u“
cf bind-service mql.uiworkout.node “MQ Light-7u“
