Details

    Description

      Add pages access and page read from disk to table stats.

      MDEV-31558 Add InnoDB engine information to the slow query log
      already collects this information from InnoDB.
      Note that for tables with foreign keys, page statistics will also include any
      pages access to foreign key tables. This cannot be easily fixed until foreign key
      handling is moved from inside InnoDB to the upper layer. However this disturbance
      in statistics should not make the statistics unusable.

      To be implemented to add PAGES_ACCESSED and PAGES_READ_FROM_DISK columns to table_stats
