Can TiDB modify the user set during cluster deployment, or if a new cluster is created, can the data from the original cluster be inherited?

I haven’t tested it. I feel it shouldn’t be modified directly because the user parameter is at the global level. If the new configuration for scaling includes new users, there might be permission issues. You can test it if you have the environment.

Take a look at this, the central control machine is lost, you can create a new one, and the data can still be used normally.
