[Reproduction Path] What operations were performed to cause the issue
The documentation states that when deploying a pump node, you need to update and restart tidb_servers. Is restarting the tidb server only necessary because the documentation sets enable_binlog = True? If the existing cluster already has enable_binlog = True, and you are just expanding the pump, is it unnecessary to restart the tidb server? I tested expanding the pump without restarting the tidb server and didn’t notice any issues in the monitoring and logs. Are there any potential risks?
