MySQL 9.4 Release Notes
        
      MySQL Keyring originally implemented keystore capabilities using
      server plugins, but began transitioning to use the component
      infrastructure in MySQL 8.0. The transition includes revising the
      underlying implementation of keyring plugins to use the component
      infrastructure. This is facilitated using the plugin named
      daemon_keyring_proxy_plugin that acts as a
      bridge between the plugin and component service APIs, and enables
      keyring plugins to continue to be used with no change to
      user-visible characteristics.
    
      daemon_keyring_proxy_plugin is built in and
      nothing need be done to install or enable it.
