---------------------------------------------------------------------------------------------
Handling of common problems
- Balance region scheduling is slow after capacity scale out
  - Observe if the PD Monitor Operator Panel generates an operator schedule and executes successfully
  - If no corresponding balance schedule is generated, further analysis is required. Possible reasons are:
    - The scheduler is not enabled, for example, the scheduler is removed, or the limit parameter is set to 0
    - Other constraints, such as the presence of evict-leader-scheduler or unreasonable label property setting, may cause some stores to fail to schedule leader or region
  - If the schedule is generating normally, but it's slow, you can try
    - View and adjust the store limit settings
    - Adjust region-schedule-limit appropriately according to business pressure
