      WL#1687 - Optimize UNION DISTINCT ... UNION ALL (again). · 784c9526
      ingo@mysql.com authored
      HEAP: Copies the key count to a backup variable and sets the key count to zero.
      That way, no HEAP function will ever try to touch any index.
      Re-enabling is done by copying back the backup variable.
      To avoid memory leak at table close, disable deletes all index trees.
      Re-enabling must be done with empty indexes and data anyway. Otherwise,
      the indexes would need to be repaired, wich HEAP is not capable of.
      MyISAM: Only the key_map is cleared and set.
      Re-enabling must be done with empty indexes and data. Otherwise, repair needs
      to be done which will enable all keys persistently.
      The former implementation disabled only non-unique keys and maked this persistent.
      The new implementation additionally can disable all keys, but only without
      making this persistent. Re-enabling all keys can be done without repair,
      if data file and indexes are empty.
