The Stream service enables asynchronous flow of data between processes in Pega Platform. The Stream service is a multi-node component that is based on Apache Kafka.

You can use this service, for example, to pass correspondence data to delivery channels in Pega Customer Decision Hub, process customer responses for the Adaptive Decision Manager (ADM), 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 replicated to other nodes in the cluster.
