Idea:

1. the client sends a request
2. the server receives the request and starts to count the data volume to be processed.
3. sort the data to be processed according to certain rules and send them to the server processing end.
4. the server processing end processes the first data and sends the processing result to the client after some processing.
5. when the client receives the result, it automatically displays the result and sends it to the server.
6. the server receives the processing result and forwards it to the server processing end.
7. the processing end continues to process the results...
8. loop through steps 4-7 until the processing is completed
