Building Data Agents Using the Messaging Functions

What Is Message Queuing

Message queuing is a communication tool that allows applications to reliably interconnect in a distributed environment where one of the applications may or may not be available at any given time. The queue acts as a holding container for messages as they are sent between applications. The applications send messages to and read messages from queues to communicate back and forth. An application writes a message to a queue, which will then be received and processed by another application at some point determined by the receiving application. This type of communication is designed for asynchronous use where the applications involved are not waiting for an immediate response from the other end.

What are Data Agents

Data agents are applications written in the Recital scripting language that use the message queue functions to manage the transmitted data. Typically a data agent runs in the background reading data from the message queue and processing it.
