C# Application Insights从自定义数据源清除数据

我通过Azure函数按计划将自定义数据加载到application insights应用程序中。工作流实质上是将一个json文件加载到azure存储帐户上，调用post到一个特定端点，其主体包含指向json文件的sas令牌链接，然后发生摄取循环，将json加载到自定义数据源中。我注意到的是，摄取周期将旧记录与新的JSON结合起来，我需要在触发新摄取之前清除数据，以便JSON文件始终表示数据集的完整状态

是否有任何API用于以编程方式清除应用程序自定义数据源中的数据

是的，可以清除Application Insights数据，但也可以 操作需要一段时间（例如2-3天）才能完成

这是通过向Azure管理API发送POST请求来实现的，如下所示：

---请求URL（POST）--

    }
  ]
