Stream node configurations for a Queue Processor rule

Updated on April 5, 2022

A Queue Processor rule requires at least one stream node to run. Without a stream node, messages cannot be queued to or retrieved from the Kafka server.

Stream nodes

A Pega node works as a stream node when you start it with a stream node type. The following JVM argument shows a stream node type: 

-DNodeType=Stream
A universal node type also works as a stream node type. The following JVM argument shows a universal node type: 
-DNodeType=Universal
If you do not define a stream node in a cluster, the items are queued to the database, and then these items are processed when a stream node is available.

Configure stream nodes by using dynamic system settings. For more information, see Using dynamic system settings.
