[DISCUSS] Planning Flink 1.13

[dwysakowicz]

Hi all,
With the 1.12 being released some time ago already I thought it would be
a good time to kickstart the 1.13 release cycle.

What do you think about Guowei and me being the release managers for
Flink 1.13? We are happy to volunteer for it.

The second topic I wanted to raise was the rough timeline for the
release. According to our usual 3 months + the release
testing/stabilising period
we should aim with the feature freeze for the end of March/beginning of
April. Does that work for everyone?

Let me know what you think.

Best,
Dawid

[Xintong Song]

Thanks for kicking off the 1.13 release cycle and volunteering as the
release managers.

+1 for Dawid & Guowei as the 1.13 release managers.
+1 for targeting feature freeze at the end of March

Thank you~

Xintong Song

Thanks for volunteering as the release managers for the 1.13 release Guowei
and Dawid. I'd also be in favour of targeting the end of March as the
feature freeze date.

I've created a 1.13 wiki page [1] where we can collect the features we want
to complete for the 1.13 release.

Thanks for doing this!

Some teams are currently doing (or already finalizing) the "usability
sprint". I was wondering whether it makes sense to release the implemented
features without waiting for the major changes. If it works well we could
decide to shorten the next release as well.

Roman

Hey Roman,

Thanks for the idea! Personally I am a bit torn about this. We have
never done something like this before. In principle I like the idea of
shorter release cycles. However I am bit skeptical about the timing to
do it now. Do we know what would be included in such a release? I am a
bit afraid it would come as a surprise for many teams unaware of plans
for a shorter release. How would we make sure that features of such
teams that ends up on master in the meantime won't interfere with the
finished features of the teams that were prepared for that shorter cycle?

What do others think about having a shorter release?

Best,

Dawid

[dwysakowicz]

Hi all,

Thank you all for a warm reception as release managers. We are also glad that the majority agrees we should aim for the end of March as the feature freeze date.

1. Till created a page in our wiki to gather potential features that we want to include in the release. Thank you Till! We'd kindly ask all committers to fill in the page with features that they intend to work on. We'd prefer if only new features end up there and not all bugs/tasks separately so that the page is not over bloated. Of course, unless fixing a bug is a really big or important one equivalent to implementing a completely new feature. In our opinion a good rule of thumb would be that each entry in the page could (but does not have to) be later on included in a release blog post.
   

The page can be accessed at: https://cwiki.apache.org/confluence/display/FLINK/1.13+Release

It would really help us if we knew what are the most critical features in the release, so that we could keep a closer eye on those as potential reasons for a delay or make a decision to cut the scope sooner. We were thinking if it would be possible to mark certain features as "release blockers". There should be no more than a single, unfinished one per committer at a time. What do you think of that idea?

2. Similarly to the previous release we would like to emphasize the importance of keeping the build and tests stable. We think that worked pretty well in the last release. Starting this week we will monitor any build and/or test instabilities. Please expect nagging for a fix ;)

You can check the current blockers in a dedicated kanban board here: https://issues.apache.org/jira/secure/RapidBoard.jspa?rapidView=445

3. One of the biggest complaints for the past release(s) was lack of proper documentation. Some features don't have a proper documentation even though they were implemented a couple of releases ago. We'd like to remind everyone that a decent documentation should always come hand in hand with the code. We have even a checkmark for it in our PR template. ;) Lets try to improve the situation a bit here! We should no longer allow ourselves to postpone writing documentation to after the feature freeze.
   

Your release managers,
Guowei & Dawid

[Khachatryan Roman]

Hey Dawid,

Replying to your penultimate message:
> We have never done something like this before
I thought releasing usability features can be such an experiment. My
reasoning is the following. As each release requires coordination of all
the participating teams, it will not scale beyond some point. And Flink is
growing rapidly. So we need to cut the scope of each release:
- either by sub-project (i.e. separate release for each component; I think
no one wants it?)
- or by time/feature set (i.e. more frequent lightweight releases)

> However I am bit skeptical about the timing to do it now.
I guess you are right. We should probably start release planning before the
previous one is completed. So maybe 1.14 :)

I think if anyone else is interested we can continue discussion in a
separate thread.

Thanks again for driving this effort!

Regards,
Roman

>    though they were implemented a couple of releases ago. We'd like to remind
>    everyone that a decent documentation should always come hand in hand with
>    the code. We have even a checkmark for it in our PR template. ;) Lets try
