Real-time event processing
Real-time event processing empowers enterprises to detect meaningful patterns in the real-time flow of events and to react to them in a timely manner. By detecting event patterns, it is possible to identify the most critical opportunities and risks.
Components of Pega 7 real-time event processing
Real-time event processing is implemented by using the following components:
- Stream Data Set – Processes a continuous data stream of events. It can take in high volumes of low-latency data. You can use this type of data set to save data to the stream and to browse data from the stream.
Event Strategy – A visual representation of processing logic that is applied to all incoming events. Event strategies can be used to specify patterns of events, query them across a data stream, and react to the emerging patterns.

Data Flow - Connects a data stream and static data sources to an event strategy. Data flows can be modified to support real-time runs, and can be used to manage data that is coming in at a high speed and to provide followup actions.

In the primary Data set pattern, you must specify the data set from which you want to import data.
For real-time processing, you must select a Stream data set to provide a continuous data stream of events.
When the data enters a data flow, an event strategy that is referenced from the Event Strategy pattern queries for events patterns across the data stream and reacts to the emerging patterns.
