@rleungx 上面@okJiang 说的有道理，我们在执行 command show 的时候能不能把 audit、rate-limiter 都隐藏掉呢？否则容易误用，既：文档里不暴露，命令行里(或者server 侧直接禁用掉、不返回)也隐藏掉

-`service-middleware` 是 PD 中的一个配置模块，主要用于管理和控制 PD 服务的中间件功能，如审计和请求速率限制等。从 v8.5.0 起，你可以通过 `service-middleware` 控制以下 gRPC API 请求的速率和并发度：

业务报错

这是不是太严重了😂

这一段可以放在后面一点的位置，放在前面，用户还不知道 请求速率限制和并发限制 是什么

还有，请求速率限制和并发限制 是 HTTP 的还是 gRPC 的，还是都不建议使用？

都不建议

放在后面感觉不够警示？

如果都不建议设置的话，可以放在

audit: 审计功能

rate-limit: 用于限制 HTTP API 请求的最大速率和最大并发

grpc-rate-limit: 用于限制 gRPC API 请求的最大速率和最大并发

后面，就直接说不建议设置 rate-limit/grpc-rate-limit 可以吧。这样就很明确了

不是，只暴露三个

这里不写“三个”也可以，不影响理解。而且，以后要是新增或减少了支持的 API 请求个数，也避免了忘记修改这里
