Polling means the client actively queries job status from the server at fixed intervals; it is simple to implement and broadly compatible, but generates many wasted requests and has latency, while subscription uses server push via WebSocket or SSE and is highly real-time but requires maintaining long connections, which is less friendly to mobile and weak networks.
