AMPS message queues provide a high-performance way of distributing messages across a set of workers. The AMPS User Guide describes AMPS in detail, including the features of AMPS referred to in this chapter. This chapter does not describe message queues in detail, but instead explains how to use the AMPS C++ client with message queues.

To publish messages to a message queue, publishers simply publish to any topic that is collected by the queue. There is no difference between publishing to a queue and publishing to any other topic, and a publisher does not need to be aware that the topic will be collected into a queue.

Subscribers must be aware that they are subscribing to a queue, and acknowledge messages from the queue when the message is processed.
