MySQL 9.1 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.
