Publish and Subscribe (Magic xpi 3.x)

Publish and Subscribe (PSS) is a way of distributing information in your network. PSS means that when an event occurs in your integration project, flows that are subscribed to the event are invoked.

The concept is the same as having a magazine subscription. When you subscribe to the magazine, you do not need to constantly check for the latest edition. The publisher sends you the latest edition when the magazine is published. The benefit of using the PSS method is that your systems do not need to constantly refresh and check for new information, and this saves system resources.

A Magic xpi PSS system has its own database containing the subscription information. When a publishing event occurs, the PSS system sends an invocation request to all the subscribed flows, even on different Magic xpi servers.
