 * When the non-null default value for a particular parameter type cannot be provided by {@code

- Server-side encryption - The Select API supports querying objects that are protected with server-side encryption.

Type inference and automatic conversion of values is performed based on the context when the value is un-typed (such as when reading CSV data). If present, the CAST function overrides automatic conversion.

与*路径操作*通信时，以下面的方式发送两个 HTTP 请求头：

```
X-Token: foo
X-Token: bar
```

响应结果是：

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## 小结

使用 `Header` 声明请求头的方式与 `Query`、`Path` 、`Cookie` 相同。

- **Focus**:
  1. Deployment of Istio using Helm charts.
  1. Verification of Helm chart configurations.
  1. Testing of Helm chart upgrades and rollbacks.
  1. Validation of custom Helm values and overrides.
  1. Ensuring compatibility with different Kubernetes versions.
- **Setup**: The main test setup in this folder initializes the Istio control plane using Helm charts.
