Which role initiates a workspace run in a Flow when triggered by a user action?

• A. Job Submitter
• B. Data Streaming
• C. Data Download
• D. Job Sender

Answer: (A)

In Flow, the action of starting a workspace run in response to a user trigger is performed by the role that submits jobs to run workspaces. The Job Submitter has the permission to initiate and queue a workspace run when the user triggers it, making it the one that actually starts the run. Data Streaming relates to feeding data into or out of a running workspace, not starting the run itself. Data Download deals with retrieving results after a run, and Job Sender implies dispatching a job elsewhere rather than kicking off the run inside the Flow. So, the initiator of a user-triggered workspace run is the Job Submitter.
