Columns added to TABLE_STATISTICS - ROWS_INSERTED, ROWS_DELETED, ROWS_UPDATED, KEY_READ_HITS and KEY_READ_MISSES. Columns added to CLIENT_STATISTICS and USER_STATISTICS: - KEY_READ_HITS and KEY_READ_MISSES. User visible changes (except new columns): - CLIENT_STATISTICS and USER_STATISTICS has columns KEY_READ_HITS and KEY_READ_MISSES added after column ROWS_UPDATED before SELECT_COMMANDS. Other changes: - Do not collect table statistics for system tables like index_stats table_stats, performance_schema, information_schema etc as the user has no control of these and the generate noice in the statistics. - All row variables that are part of user_stats are moved to 'struct rows_stats' to make it easy to clear all of them at once. - ha_read_key_misses added to STATUS_VAR Notes: - userstat.result has a change of numbers of rows for handler_read_key. This is because use-stat-tables is now disabled for the test.
