The MYSQL_FIREWALL_USERS table
      provides a view into the in-memory data cache for MySQL Enterprise Firewall. It lists
      names and operational modes of registered firewall account
      profiles. It is used in conjunction with the
      mysql.firewall_users system table that provides
      persistent storage of firewall data; see
      MySQL Enterprise Firewall Tables.
    
      The MYSQL_FIREWALL_USERS table has
      these columns:
- USERHOST- The account profile name. Each account name has the format - user_name@- host_name
- MODE- The current operational mode for the profile. Permitted mode values are - OFF,- DETECTING,- PROTECTING,- RECORDING, and- RESET. For details about their meanings, see Firewall Concepts.
