Use Cases

8

Intensive work offloaded and distributed amongst worker processes to be performed asynchronously

- Processing images or videos- Performing text analytics

Event Driven

Take one or more actions when something interesting happens

- Email logs and update dashboards when build finishes- Upload videos once finished transcoding

Worker Offload

Use Cases

9

Schedule a task to happen at a specific point in time

- Run in detailed reports when app use is low- Generate end of day summary

Ensure applications remain responsive even when 3rd party system are not available or responding fast enough

- Updating existing CRM system- Booking appointment

Delayed Processing

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

© 2014 IBM Corporation16

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. Send (‘/test/a’, “Hello”);2. Send (‘/test/a’, “World!”);

1. Hello2. World!

Topic Address Space

Sender application

DESTINATIONPattern=/test/a

© 2014 IBM Corporation17

MQ Light Messaging Model – Pub/Sub

•Multiple destinations can be created which match the same topic• Pub/Sub style.

DESTINATION

1. Send (‘/test/a’, “Hello”);2. Send (‘/test/a’, “World!”);

1. Hello2. World!

1. Hello2. World!

Topic Address Space

Sender application

DESTINATIONPattern=/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.

1. Send (‘/test/a’, “Hello”);2. Send (‘/test/a’, “World!”);

Topic Address Space

Sender application

HelloWorld!

DESTINATIONPattern=/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”);2. Send (‘/test/a’, “World!”);

1. Hello2. World!

1. Hello

2. World!

SHARING

MQ Light Messaging Model – Client takeover

1. Send (‘/test/a’, “Hello”);

Hello

Topic Address Space

Sender application

DESTINATIONPattern=/test/#

Client 1

World!

Client 1

2. Send (‘/test/a’, “World!”);

•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 Messaging Model

Messages– Payload is either Text or Binary.– Content-type is used by clients to transfer JSON– Per message time to live.

Message delivery model– At most once delivery (QoS 0)– At least once delivery (QoS 1)– Acknowledge & Reject messages– Control over the number of unacknowledged messages delivered. (link credit)

MQ Light Node.JS API. Installable from NPM

Promotes a fluent programming style

Easily wrappable into promises.

Focussed on code simplicity.

Client - connect state machine– Assists cloud applications.

 client.connect()        .on('connected', function() {            console.log('Have some random cat names.  Have them!');            subscribe('/kittens');        })        .on('disconnected', function() {            console.log('That's enough for now!');        })        .on('message', function(data) {            console.log('Why not call your cat: '+data);        });
