Configuring the Data Flow service

The Data Flow service enables running data flow work items on decision data. To enable the Data Flow service, you must add at least one decision data node on the Data Flow tab of the Services landing page. You can add additional decision data nodes to scale the processing of data. Each new data flow work item is processed on all nodes that are listed in this tab.

Note: Test runs of data flows are always processed on the local Pega 7 Platform node, so you do not configure the Data Flow service for test runs.

1. Click Designer Studio > Decisioning > Infrastructure > Services > Data Flow.
2. Add a node:
   1. Click Add node.
   2. In the window that is displayed, select the check box for the decision data node that you want to add. You can add multiple nodes at once.
   3. Click Submit.
   4. Refresh the landing page until the status of the node changes to NORMAL.
3. Optional: Specify the number of the Pega 7 Platform threads that are assigned to process running the data flows:
   1. Click Edit settings.
   2. In the window that is displayed, enter the number of threads in the Thread count field.

   Note: The number of threads for running data flows is the same across all decision data nodes that are configured for the Data Flow service.

4. Optional:  Display the details for a particular node by clicking the row for that. You can view the node ID number, status details, and the number of active data flow runs.
5. Optional: Manage a node by selecting an action from the Execute menu.

   Note: If you decommission a node that has active data flow runs, the status of that node changes to LEAVING, and it is not decommissioned until all active data flow runs are finished.
