Subscribers

When a publisher sends a message, subscribers intercept the message and load it into the appropriate data store.

Subscribers are configured to listen for message deliveries from one or more publishers.

There are two primary subscribers: the RAPCache Subscriber and the RAPStore Subscriber. Because RAP is intended to provide immediate data access and persistent data storage, both subscribers should listen for message deliveries from the same publishers (though this is not a must). This ensures that the same data is loaded into the RAPCache database and the RAPStore database at the same time.

In addition to the two primary subscribers, there is also a Demo Subscriber which is designed to demonstrate how messages flow through RAP.

• RAPCache Subscriber
  The RAPCache Subscriber receives messages from publishers and then loads them into the RAPCache database.
• RAPStore Subscriber
  The RAPStore Subscriber receives messages from publishers and then loads them into the RAPStore database.
• Demo Subscriber
  Demo Subscriber is designed to demonstrate (in conjunction with the Demo Feed Handler) how messages flow through RAP.
