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。
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。
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。
