Node types for on-premises environments

Version:

Only available versions of this content are shown in the dropdown

Pega Platform provides a set of node types which you can assign to a node in your system. You can associate these node types with resources in order to optimize performance.

Pega-provided node types

You can use the following Pega-provided node types to segregate work in your Pega application:

  • BackgroundProcessing - Performs background utility processing
  • BIX - Performs Business Intelligence Exchange (BIX) data extractions for clients with BIX subscriptions
  • Search - Performs search indexing using Elasticsearch
  • Stream - Performs Kafka-based stream processing for Queue Processors in any Pega application, as well as for Pega Customer Decision Hub and Pega DSM subscriptions
  • WebUser - Performs web application processing
  • Universal - Performs processing for all of the Job Schedulers, Queue Processors, agents, and listeners on these nodes. As a best practice, avoid using the Universal node type in a production environment.

    Additional node type considerations:

    • RunOnAllNodes - This is not a node type you can start a node with, however you can associate this node type option with a work resource when you want it to run on all the node types.
    • If you do not assign a node type to a node, Pega Platform, by default, associates the node with four Pega-provided node types: "BackgroundProcessing,Search,Stream,WebUser".

Decision Strategy Manager node types

In Pega Decision Strategy Manager (DSM), you can use the following Pega-provided node types to further segregate DSM-related work in your Pega application:

  • ADM - Runs the Adaptive Decision Manager (ADM) service
  • Batch - Runs DSM background processes
  • DDS - Runs the Decision Data Store (DDS) service for Cassandra-related data processing
  • RealTime - Runs realtime processes such as processing user requests in the context of DSM
  • RTDG - Runs the Real Time Data Grid (RTDG) service
