The firewall_groups table
          provides a view into the in-memory data cache for MySQL Enterprise Firewall. It
          lists names and operational modes of registered firewall group
          profiles. It is used in conjunction with the
          mysql.firewall_groups system table that
          provides persistent storage of firewall data; see
          MySQL Enterprise Firewall Tables.
        
          The firewall_groups table has
          these columns:
- NAME- The group profile name. 
- MODE- The current operational mode for the profile. Permitted mode values are - OFF,- DETECTING,- PROTECTING, and- RECORDING. For details about their meanings, see Firewall Concepts.
- USERHOST- The training account for the group profile, to be used when the profile is in - RECORDINGmode. The value is- NULL, or a non-- NULLaccount that has the format- user_name@- host_name- If the value is - NULL, the firewall records allowlist rules for statements received from any account that is a member of the group.
- If the value is non- - NULL, the firewall records allowlist rules only for statements received from the named account (which should be a member of the group).
 
          The firewall_groups table has no
          indexes.
        
          TRUNCATE TABLE is not permitted
          for the firewall_groups table.
        
          The firewall_groups table was
          added in MySQL 8.0.23.
