Real Time data flows don't start back up on Node restart

SA-30372

Summary



User have real time data flows configured (Designer Studio -> Decisioning -> Decisions -> Data Flows -> Real Time Processing). These data flows are used for processing events being sent to Stream Data sets in the application.

Whenever there is a node restart, we see these flows changed to "Failed" status and we need to manually restart them. This is not ideal, as these are part of always on logic for business application and this adds additional burden on the Admin team to check and restart the flow on each restart.


Error Messages


Not Applicable


Steps to Reproduce



1. Configure a Data Flow to execute as real time processing flow.
2. Restart the node.
3. Check the status on restart - it has changed to Failed.

Resolution
