Stream service
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 to, for example, pass correspondence data to delivery
channels in Pega Marketing, 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.
The Stream service is built on the Apache Kafka platform. To better understand Kafka-related terminology, see the Apache Kafka documentation.
