功能概述
分布式数据库 TDSQL MySQL 版提供透明数据加密（Transparent Data Encryption，TDE）功能，透明加密指数据的加解密操作对用户透明，支持对数据文件进行实时 I/O 加密和解密，在数据写入磁盘前进行加密，从磁盘读入内存时进行解密，可满足静态数据加密的合规性要求。
说明：
注意事项
目前实例 开启密钥管理系统 KMS 后，不可创建灾备/只读实例。
TDE 加密功能开通后无法关闭。
开启 TDE 加密功能后，可提高静态数据的安全性，但同时会影响访问加密数据库的读写性能，请结合实际情况选择开启 TDE 加密功能。
开启 TDE 加密功能后，会增加 CPU 资源的消耗，大约会影响5%左右的性能。
