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

将示例记录写入指定的目标，以帮助您验证 Amazon Glue 作业执行的转换。

## 示例
<a name="pyspark-spigot-examples"></a>

我们建议您使用 [`DynamicFrame.spigot()`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#aws-glue-api-crawler-pyspark-extensions-dynamic-frame-spigot) 方法将 `DynamicFrame` 中的记录子集写入指定的目标。要查看代码示例，请参阅 [示例：使用 spigot 将 `DynamicFrame` 中的示例字段写入 Amazon S3](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#pyspark-spigot-example)。

## \_\_call\_\_(frame, path, options, transformation\_ctx = "")
<a name="aws-glue-api-crawler-pyspark-transforms-spigot-__call__"></a>

在转换期间将示例记录写入指定的目标。
+ `frame` – 要执行 spigot 操作的 `DynamicFrame` (必需)。
+ `path` – 要写入的目标的路径（必需）。
+ `options` – 指定选项的 JSON 键值对（可选）。`"topk"` 选项指定应写入的第一个 *k* 记录。`"prob"` 选项指定选择任何给定记录的可能性（以十进制数字形式表示）。您可以在选择要写入的记录时使用它。
+ `transformation_ctx` – 用于标识状态信息的唯一字符串 (可选)。
