For now Zaqar's websocket transport can only send and receive text messages in JSON format. By using messages in binary format it's possible to reduce network traffic between Zaqar server and it's clients. In most cases it's also possible to increase performance. This patch implements support for binary messages over websocket transport in Zaqar server. The MessagePack format was chosen for encoding/decoding messages as it's effective enough and available in convenient libraries for most programming languages. This patch also modifies "examples/websockets.html" example to be able to send and receive binary messages. All "print" function calls are substituted to local logger calls. DocImpact APIImpact The patch adds new functionality. Now sending binary request over websocket doesn't automatically return response with code 400, because now websocket transport is able to process binary requests encoded in MessagePack. blueprint: websocket-binary-support Change-Id: I07a7c46795e3b510ee397a6d2c4665e770c2c4b2
Zaqar
Zaqar is a multi-tenant cloud messaging and notification service for web and mobile developers. It combines the ideas pioneered by Amazon's SQS product with additional semantics to support event broadcasting.
The service features a fully RESTful API, which developers can use to send messages between various components of their SaaS and mobile applications, by using a variety of communication patterns. Underlying this API is an efficient messaging engine designed with scalability and security in mind.
Other OpenStack components can integrate with Zaqar to surface events to end users and to communicate with guest agents that run in the "over-cloud" layer. Cloud operators can leverage Zaqar to provide equivalents of SQS and SNS to their customers.

Using Zaqar
If you are new to Zaqar and just want to try it, you can set up Zaqar in the development environment.
Using Zaqar in production environment:
Coming soon!
Using Zaqar in development environment:
The instruction is available at:
http://docs.openstack.org/developer/zaqar/devref/development.environment.html
This will allow you to run local Zaqar server with MongoDB as database.
This way is the easiest, quickest and most suitable for beginners.
