Improvements

  • Split and scatter Regions concurrently to improve restore speed #1429
  • Retry BR tasks when encountering the PD request error or the TiKV I/O timeout error #1433
  • Reduce empty Regions when restoring many small tables to avoid affecting cluster operation after the restore #1374 #1432
  • Perform the rebase auto id operation while creating tables, which saves the separate rebase auto id DDL operations to speed up restore #1424

Bug fixes

  • Fix a bug that the average speed is inaccurate in backup and restore #1410
