> Project: Spark
> Issue Type: Documentation

> Affects Versions: 3.5.0
> Reporter: Jungtaek Lim
> Assignee: Jungtaek Lim

> Fix For: 3.4.1, 3.5.0
>
>
> We made a change on the guide doc for SPARK-40925 via SPARK-42105, but from
> SPARK-42105 we only removed the section of "limitation of global watermark".
> That said, we haven't provided any example of new functionality, especially
> that users need to know about the change of SQL function (window) in chained
> time window aggregations.
> In this ticket, we will add the example of chained time window aggregations,
> with introducing new functionality of SQL function.
