Hi Dawid, Joe & Xintong,
Thanks for starting the discussion.
I would like to polish Window TVFs[1][2] which is a popular feature in SQL
introduced in 1.13.
The detailed items are as follows.
1. Add more computations based on Window TVF
* Window Join (which is already merged in master branch)
* Window Table Function
* Window Deduplicate
2. Finish related JIRA to improve user experience
* Add offset support for TUMBLE, HOP, session window
3. Complement the missing functions compared to the group window, which is
a precondition of deprecating the legacy Grouped Window Function in the
later versions.
* Support Session windows
* Support allow-lateness
* Support retract input stream
* Support window TVF in batch mode

> new features that will likely be included in this release. We have created
> a wiki page [1] for collecting such information. We'd like to kindly ask
> all committers to fill in the page with features that they intend to work

> merge PRs through the Github button, but do this manually, with caution for
> the commits merged after the CI being triggered. It would be appreciated to
> always build the project before merging to master.

> - Documentation: Please try to see documentation as an integrated part of
> the engineering process and don't push it to the feature freeze phase or
> even after. You might even think about going documentation first. We, as
> the Flink community, are adding great stuff, that is pushing the limits of
> streaming data processors, with every release. We should also make this
> stuff usable for our users by documenting it well.
>
> - Promotion of 1.14: What applies to documentation also applies to all the
> activity around the release. We encourage every contributor to also think
> about, plan and prepare activities like blog posts and talk, that will
> promote and spread the release once it is done.
>
> Please let us know what you think.

> Thank you~
