Hi devs, The Row-Count-Window must require proctime at Table API, and the
definiton for Row-Count-Window like the [1].In fact I don't understand it. The
countWindow is based on a window (range) of preceding and succeeding rows, but
not the time. Thedefinition [2] for Row-Count-Window maybe friendly for users.
[1] ".rowWindow(TumbleRows over 10.rows on ‘proctime as ‘w)".
[2] .rowWindow(TumbleRows over 10.rows as ‘w)
Thanks,
John Fang
