Kafka process runs for each node post application upgrade
Post upgrade to Pega 8.2.1, a Kafka process runs for each Pega JVM which consumes CPU storage. This results in performance degradation.
Steps to Reproduce
The Kafka process runs on Stream nodes and at least one Stream node is required for the Pega application to run. Unless otherwise specified, an 8.2.x node defaults to Background Processing, Search, WebUser, and Stream types.
ResolutionPerform the following local-change:
To specify the node type, add the following JVM argument with a valid node type value such as WebUser:
If the node is a Stream node, navigate to Dev Studio > Configure > Decisioning > Infrastructure > Services > Stream, and decommission the node. Restart it after applying the JVM argument.
