具有动态持续时间的翻滚窗口

Question

While passing reference data field as a duration in TumblingWindow I am getting compile time error related to Window duration require positive float constant.

Can anyone please guide?

group by TumblingWindow(minute, referencetable.EntryTime)

At the moment we don't support variable time windows, so you need to set the time explicitly and not load it from the reference data. Sorry for the inconvenience.

A workaround, in the case you have only few different time durations, would be to have different steps/subqueries for the different times and use a where clause to create or not an output for that step.

Let me know if you have further question.
