Description

The SHOW TABLE_STATISTICS statementis part of the User Statistics feature. It was removed as a separate statement in MariaDB 10.1.1, but effectively replaced by the generic SHOW information_schema_table statement. The information_schema.TABLE_STATISTICS table shows statistics on table usage

The userstat system variable must be set to 1 to activate this feature. See the User Statistics and information_schema.TABLE_STATISTICS articles for more information.
