    Description

      Hi,

      I think it is useful to add some status counters for implicit temporary tables. The created_tmp_tables vs created_tmp_disk_tables does not always do the trick.

      Can you add:

      • How many bytes were written to implicit temporary tables
      • How many bytes were written to implicit temporary tables on disk
      • How many temporary tables on disk were created because the MEMORY storage engine did not support the schema
      • How many temporary tables on disk were created because the max_tmp_table_size or max_heap_table_size was reached

      Feel free to split up if some are more difficult then others, any part of this would be a significant improvement.

      Thank you!
      Michaël
