Support New Type of Window about ekuiper HOT 4 OPEN

Check the conditional sliding window https://ekuiper.org/docs/en/latest/sqls/windows.html#the-trigger-condition-of-the-sliding-window

this is the demo in https://docs.tdengine.com/taos-sql/distinguished/#event-window

select _wstart, _wend, count(*) from t event_window start with c1 > 0 end with c2 < 10 

And this is the version I translated into ekuiper：

SELECT count(*) FROM t GROUP BY SlidingWindow(ss,60) FILTER(where c1 > 0) OVER(when c2 < 10)

FILTER control the window started, OVER control the window closed. And (ss,60) is an additional constraint on the windows length on time. Am I right?

how to exactly control the start point of the window?
refer: https://docs.tdengine.com/taos-sql/distinguished/#event-window
td can use start with expr1 end with expr2

conditional sliding window, in my understanding, only can control end with OVER(when expr)

from ekuiper.

I don't think conditional sliding window meet my need. The doc mean Each piece of data meets the filtering conditions will trigger.

I want only trigger once when OVER expr, then the windows should reopen on FILTER expr
