Stream service

The Stream service enables asynchronous flow of data between processes in Pega Platform. For example, you can use this service to pass correspondence data to delivery channels in Pega Marketing, process customer responses by Adaptive Decision Manager, or initiate background processes in any Pega application.

The Stream service ingests, routes, and delivers high volumes of low-latency data such as web clicks, transactions, sensor data, work objects, data pages, and customer interaction history. As a resiliency mechanism for operations, the same data is is replicated to other nodes in the cluster. For on-premises deployments and applications, you can add extra Stream nodes to increase the volume of data that is handled by your decision management processes or to reduce latency in making decisions.

The Stream service is built on the Apache Kafka platform. To understand Kafka-related terminology, see the Apache Kafka documentation.
