Hi all,

Just wanted to know if there is any documentation regarding window
functions ? Specifically if I have to do something like : "count(*) over
window", I somehow can't find any examples on the Calcite docs.

More specifically,
* Is there a way to specify a time window range ?
* Assuming I have a timestamp column, can I use that to define the window
range ?
* Is there any implementation of Streaming SQL out there that I can use ?

Any help would be much appreciated.
