      intent: Run a query against a dataflow and get results
      effect: read
      questions:
      - How do I run one of a dataflow's queries and stream the result back to my app?
      - How long can a query executed against a dataflow run before it times out?
      - Can I get dataflow query results back as an Apache Arrow stream?
      instructions:
      - text: Execute a query against dataflow {dataflowId} in workspace {workspaceId} and return the rows.
        slots:
          dataflowId: path.dataflowId
          workspaceId: path.workspaceId
      - text: Run a query on dataflow {dataflowId} and return the result as {Accept}.
