 #### 使用数据库访问统一接口
+
 ```go title="原生连接"
 {{#include docs-examples/go/connect/cgoexample/main.go}}
 ```
+
 ```go title="REST 连接"
 {{#include docs-examples/go/connect/restexample/main.go}}
 ```
+
 #### 使用高级封装
+
 也可以使用 driver-go 的 af 包建立连接。这个模块封装了 TDengine 的高级功能, 如：参数绑定、订阅等。
 
 ```go title="使用 af 包建立原生连接"
 {{#include docs-examples/go/connect/afconn/main.go}}

-使用REST 连接时，如果查询数据量比较大，还可开启批量拉取功能。

 :::note
 对于 Rust 连接器， 连接方式的不同只体现在使用的特性不同。如果启用了 "rest" 特性，那么只有 RESTful 的实现会被编译进来。

 ```csharp title="Native Connection"
 {{#include docs-examples/csharp/ConnectExample.cs}}
 ```
+
 :::info
 C# connector supports only native connection for now.
 

docs-en/04-develop/01-connect/_connect_go.mdx

 #### Unified Database Access Interface
+
 ```go title="Native Connection"
 {{#include docs-examples/go/connect/cgoexample/main.go}}
 ```
+
 ```go title="REST Connection"
 {{#include docs-examples/go/connect/restexample/main.go}}
 ```
+
 #### Advanced Features
+
 The af package of driver-go can also be used to establish connection, with this way some advanced features of TDengine, like parameter binding and subscription, can be used.
 
 ```go title="Establish native connection using af package"
 {{#include docs-examples/go/connect/afconn/main.go}}

 When using REST connection, the feature of bulk pulling can be enabled if the size of resulting data set is huge.
 
 ```java title="Enable Bulk Pulling" {4}
 {{#include docs-examples/java/src/main/java/com/taos/example/WSConnectExample.java:main}}

 :::note
 For Rust connector, the connection depends on the feature being used. If "rest" feature is enabled, then only the implementation for "rest" is compiled and packaged.
