Workflow on Secondary Worker

Question

Hello,

I'm curious what would happen to a workflow actively being processed on a secondary worker when the primary node (hosting the Gallery/MongoDB/Worker) is told to stop the AlteryxService (ie. to initiate a MongoDB backup).  I understand the AlteryxService will wait for any instances of AlteryxEngineCmd.exe to complete; however, if these processes are being executed on a separate host machine, what is the behavior?

Any advice would be greatly appreciated!

Thanks.

Ah; good question.  Haven't encountered that before.  My guess is that since the Service's job is just to start/stop jobs and apps that it would finish executing.  But don't quote me!

@mbarone thanks for the response.  What's the behavior when you initiate a stoppage of the AlteryxService on the controller while a workflow is actively processing on the worker-only node?  Does it hang at 'stopping' until that job is completed?

I only have my own anecdotal experience to speak of (as opposed to the technical aspect behind a controller/worker).  When the Alteryx service on our Controller stops, the service on our secondary worker-only node also stops.
