Regarding to **L.window_start = R.window_start AND L.window_end =
R.window_end**:
In general, the current table function windowing model is to append window
metadata to table directly, thus window metadata becomes a part of table
(or call it data). So as a part of table, these two columns should b
Is there any possibility that 1.26.0 can be released in the following weeks,

window table function ~
For example, we can define a tumbling window function of 5 minutes size as:
Tumble(table T, descriptor(T.ts), INTERVAL ‘5’ MINUTE)

Is there a better way?
I'm am idealist with regard to streaming SQL semantics, and I'm going
