I just extended the 'select' part of my Stream Analytics query, and suddenly get: "Query compilation error: Too many aggregate expressions."

Searching for this error yields no results, except an old, google-cached page about 'Azure Stream Analytics Preview limitations' where it is said that "The maximum number of supported aggregate functions in a Stream Analytics job query definition is 7."

But that was for the Preview of course.

=> Is it normal to get this error with the current (GA) version of Stream Analytics? What is the limit?

thanks!

每个查询的最大聚合有明确的定义 (15)。根据非缓存和非预览官方文档。

请注意，每个查询的聚合可能不超过 15 个。

如果您观察到与此不同的行为，最好引起注意 - 评论文档或打开支持票。
