Hi Kostas: Thank you for your rapid response! My use-case is that : For every incoming event, we want to age the out-of-date event , count the event in window and send the result.
For example: The events are coming as flowing: [cid:image002.png@01D22401.7DD230E0] We want flowing result: [cid:image004.png@01D22402.EF14D4A0] By the way, In StreamSQL API, in FILP11, It will realize row window. It seems that the function of Slide Event-time row-window suits my use-case. Does data stream API support row window?

So your use-case is not supported out-of-the-box. But, if you describe a bit more what you want to do, we may be able to find a way together to do your job using the currently offered functionality.
