Enhancement

  • introduce a parameter --auto-analyze to update the column modify_count of the table mysql.stats_meta to trigger tidb_analyze_priority_queue to analyze tables in the background.
  • also update the stats meta of the partition.
  • batch update the stats meta and skip updating stats meta history.
