The MYSQL_FIREWALL_WHITELIST table
      provides a view into the in-memory data cache for MySQL Enterprise Firewall. It lists
      allowlist rules of registered firewall account profiles. It is
      used in conjunction with the
      mysql.firewall_whitelist system table that
      provides persistent storage of firewall data; see
      MySQL Enterprise Firewall Tables.
    
      The MYSQL_FIREWALL_WHITELIST table
      has these columns:
- USERHOST- The account profile name. Each account name has the format - user_name@- host_name
- RULE- A normalized statement indicating an acceptable statement pattern for the profile. A profile allowlist is the union of its rules. 
This table is deprecated and subject to removal in a future MySQL version. See Migrating Account Profiles to Group Profiles.
