Improvements

  • Avoid unexpected statistics after adding the scatter region scheduler #3602
  • Solve multiple scheduling issues in the scaling process
  • Optimize the generation process of replica snapshots to solve slow scheduling issues during scaling:
  • Solve slow scheduling issues caused by heartbeat pressure due to traffic changes
  • Reduce the space discrepancies of large clusters due to scheduling, and optimize the scheduling formula to prevent the bursting issue (which is similar to heterogeneous space clusters) caused by large compression rate discrepancies #3592 #10005

Bug Fixes

  • Fix the issue that the PD Leader re-election is slow when there are many stores #3697
  • Fix the panic issue that occurs when removing the evict leader scheduler from a non-existent store #3660
  • Fix the issue that the statistics are not updated after offline peers are merged #3611
