Hi!
It seems that you want to filter some record out before they go into the
window. So why not filter them before applying the window?

Hey there,
So I have a stream of data, let the stream be a_1, a_2, a_3, a_4, a_5.
Now I would like to have a sliding window which slides by 1 second and
takes the data of 1 second. But here comes the caveat:
- I only want to keep the data in the window that does not have matching
elements.
