Dear teachers,

I would like to ask:
Assuming we have multiple PDs, is there a way to manually designate one of the PDs as the leader? I feel it should be possible. For example, when tiup restarts PD, it should switch the PD leader during the restart, right? So there should be a way to manually make a specific PD the leader?

You can use pd-ctl to transfer the leader to a specified member:
member leader transfer pd3

The pd ctl tool can be configured manually.
