清除数据

通过之前的介绍,我们了解到推送数据集没有过期时间,会将数据长期存储在数据仓库中。

那么随着时间的推移数据仓库中的数据会越来越多,占用的资源也会逐渐增加。另外,有时也会因为实际的需求去清理数据。

清除数据

首先获取清除数据的 API 信息。

从弹出的窗口中可获取到API信息,包括端点和请求体信息,以及示例报文。

文中我们以 Postman 为例为您介绍清除数据的过程。

以下为图中六个编号对应的介绍。

1. 选择类型为 DELETE,代表清除数据。

2. 与推送数据时类似,需要将 API 信息中的端点复制到URL框中。

3. 选择请求体 Body

4. 选择类型为 raw

5. 选择格式为 JSON

6. 将请求体内容复制粘贴到报文内容中。

然后按实际需求修改。

比如示例中我们如下图修改,含义是将销售金额大于400的数据清除掉。其中Option 支持 > < = 三种运算符。

  1. 填写完成后,点击发送按钮发送报文。发送成功后会有成功提示。

7. 完成报文推送后,我们来预览流数据集。可见数据清除成功,仅剩下了一条销售金额为400 的数据,大于400的都已经被清除掉。
