MySQL 8.4 Release Notes
以下部分描述了与克隆插件相关的性能模式（Performance Schema）表（参见 第 7.6.7 节，“克隆插件”）。这些表提供有关克隆操作的信息。The following sections describe the Performance Schema tables associated with the clone plugin (see Section 7.6.7, “The Clone Plugin”). The tables provide information about cloning operations.
clone_status：当前或最后一次执行的克隆操作的状态信息。clone_status: status information about the current or last executed cloning operation.clone_progress：当前或最后一次执行的克隆操作的进度信息。clone_progress: progress information about the current or last executed cloning operation.
Performance Schema 克隆表由克隆插件实现，并在该插件加载和卸载时加载和卸载（参见 第 7.6.7.1 节，“安装克隆插件”）。表不需要特殊的配置步骤。然而，这些表依赖于克隆插件被启用。如果克隆插件已加载但被禁用，则不会创建表。The Performance Schema clone tables are implemented by the clone plugin and are loaded and unloaded when that plugin is loaded and unloaded (see Section 7.6.7.1, “Installing the Clone Plugin”). No special configuration step for the tables is needed. However, the tables depend on the clone plugin being enabled. If the clone plugin is loaded but disabled, the tables are not created.
Performance Schema 克隆插件表仅在接收 MySQL 服务器实例上使用。数据在服务器关闭和重启后仍然保留。The Performance Schema clone plugin tables are used only on the recipient MySQL server instance. The data is persisted across server shutdown and restart.
