# Relationalize 类
<a name="aws-glue-api-crawler-pyspark-transforms-Relationalize"></a>

在 `DynamicFrame` 中展平嵌套架构，并从展平帧透视数组列。

## 示例
<a name="pyspark-Relationalize-example"></a>

我们建议您使用 [`DynamicFrame.relationalize()`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#aws-glue-api-crawler-pyspark-extensions-dynamic-frame-relationalize) 方法关系化 `DynamicFrame`。要查看代码示例，请参阅 [示例：使用 relatialize 在 `DynamicFrame` 中展平嵌套架构](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#pyspark-relationalize-example)。

关系化 `DynamicFrame` 并生成一个帧列表，这些帧是通过取消嵌套列的嵌套并透视数组列生成的。可使用在取消嵌套阶段生成的联接键将透视数组列联接到根表。
+ `frame` – 要关系化的 `DynamicFrame` (必需)。
+ `staging_path` – 要将 CSV 格式的透视表分区存储到的路径（可选）。从该路径读取透视表。
+ `name` – 根表的名称 (可选)。
+ `options` – 可选参数的词典。目前未使用。
+ `transformation_ctx` – 用于标识状态信息的唯一字符串 (可选)。
+ `info` – 与转换中的错误关联的字符串 (可选)。
+ `stageThreshold` – 在转换出错之前可能在其中发生的最大错误数（可选）。默认值为 0。
+ `totalThreshold` – 在处理出错之前可能全面发生的最大错误数（可选）。默认值为 0。
