Dear teachers, in the dual-center mode within the same city,

  1. There should be a specific method to fix all the region leaders of TiKV on certain machines, right?
  2. There should also be a specific method to fix the PD leader on a certain server, right?
    Please provide guidance on these two methods.

  1. (1) Set evict scheduler for machines that do not need a leader (2) Use placement rule (3) Set leader weight to 0 for machines that do not need a leader (cannot fully guarantee no leader)
  2. Set leader weight using pd-ctl member weight
