Hello Igor, I've noticed that engine-independent statistics show up in userstats: +--------------+-------------+-----------+--------------+-------------------------+ | Table_schema | Table_name | Rows_read | Rows_changed | Rows_changed_x_#indexes | +--------------+-------------+-----------+--------------+-------------------------+ | bug929732 | c2 | 249 | 0 | 0 | | mysql | index_stat | 84 | 0 | 0 | | bug929732 | v | 276 | 0 | 0 | | mysql | column_stat | 44 | 0 | 0 | | bug929732 | c | 249 | 0 | 0 | | bug929732 | v3 | 837280 | 0 | 0 | | mysql | table_stat | 12 | 0 | 0 | | bug929732 | v4 | 3994 | 0 | 0 | | bug929732 | v2 | 53506 | 0 | 0 | +--------------+-------------+-----------+--------------+-------------------------+ Is this intentional? I've also started collecting some minimal docs at http://kb.askmonty.org/en/engine-independent-table-statistics/ BR Sergei -- Sergei Petrunia, Software Developer Monty Program AB, http://askmonty.org Blog: http://s.petrunia.net/blog
