Now,Zaqar will always return "max_messages_post_size" and "default_message_ttl" when get a queue's metadata. So users can't know whether these values are in db or not. Then if they take the "replace" or "remove" action to update the queue's metadata when these two values are not in db, they will get an error: "can not update(remove) non-exist metadata". So we should check them before the queue update action. Change-Id: Ia97e80a406c8321c7e8d0aa2652023049e5ee4c0 Closes-bug: #1570160
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.
