Also, the count does not include files that storage engines open using their own internal functions rather than asking the server level to do so.

Shows the number of ongoing transactions which use  gtid_next=ANONYMOUS  and that violate GTID consistency. This status variable is only available in debug builds. Shows the number of ongoing transactions which use  gtid_next=AUTOMATIC  and that violate GTID consistency. The number of streams that are open (used mainly for logging). The number of cached table definitions. The number of tables that are open. • Max_execution_time_set_failed • Max_used_connections • Max_used_connections_time • Not_flushed_delayed_rows • mecab_charset • Ongoing_anonymous_transaction_count • Ongoing_anonymous_gtid_violating_transaction_count • Ongoing_automatic_gtid_violating_transaction_count • Open_files • Open_streams • Open_table_definitions • Open_tables • Opened_files 962
