推荐答案

以下是来自AWS支持的官方回复:

Here is the official response from AWS support:

当前，我们不支持嵌套查询，因此Insights无法实现您的用例.但是，我们可以确认在此用例的末尾存在功能请求.现在尚没有实现该功能的预计时间.我希望你明白.请注意以下链接，以了解任何新功能更新:

Currently, we do not have support for nested queries, and hence your use-case won't be achievable with Insights. However, we can confirm that we have a feature request existing at our end for this use-case. We don't have an ETA now on when this will be implemented. I hope you understand. Please keep a watch on below link for any new feature updates:

作为一种解决方法，您现在可以下载部分查询结果(运行查询->操作->导出->下载查询结果(CSV)并过滤结果以标识视频ID.请在下面找到在这种情况下可以帮助您的一个示例查询:

As a workaround, for now, you could download partial query results(Run the query -> Actions -> Export -> Download query results(CSV) and filter the results to identify the video ids. Please find below one sample query that can help you in this case:

fields @timestamp, @message
| parse @message 'REQUEST-ID:* Request=*' as REQUESTID,Request
| parse @message 'REQUEST-ID:* Video id=*' as REQUESTIDVID,Videoid
| DISPLAY REQUESTID,Request,REQUESTIDVID,Videoid
