#### SQLAlchemy 风格和 Pydantic 风格

请注意，SQLAlchemy*模型*使用 `=`来定义属性，并将类型作为参数传递给`Column`，例如：

```Python
name = Column(String)
```

虽然 Pydantic*模型*使用`:` 声明类型，但新的类型注释语法/类型提示是：

```Python
name: str
```

请牢记这一点，这样您在使用`:`还是`=`时就不会感到困惑。

- Some of the in-tree storage drivers indicate support for the `MetricsProvider` interface, but fail to configure this for BlockMode volumes. With a recent change, `Kubelet` will call `GetMetrics()` for BlockMode volumes, and the in-tree drivers that miss the support cause a Go panic. Now the in-tree storage drivers that support BlockMode volumes, will return the Capacity of the volume in the `GetMetrics()` call.
