[DISCUSS] Feature freeze date for 1.13

[Dawid Wysakowicz-2]

Hi devs, users!

1. Feature freeze date

We are approaching the end of March which we agreed would be the time for a Feature Freeze. From the knowledge I've gather so far it still seems to be a viable plan. I think it is a good time to agree on a particular date, when it should happen. We suggest (end of day CEST) March 31st (Wednesday next week) as the feature freeze time.

Similarly as last time, we want to create RC0 on the day after the feature freeze, to make sure the RC creation process is running smoothly, and to have a common testing reference point.

Having said that let us remind after Robert & Dian from the previous release what it a Feature Freeze means:

*B) What does feature freeze mean?*After the feature freeze, no new
features are allowed to be merged to master. Only bug fixes and
documentation improvements.
The release managers will revert new feature commits after the feature
freeze.
Rational: The goal of the feature freeze phase is to improve the system
stability by addressing known bugs. New features tend to introduce new
instabilities, which would prolong the release process.
If you need to merge a new feature after the freeze, please open a
discussion on the dev@ list. If there are no objections by a PMC member
within 48 (workday)hours, the feature can be merged.

2. Merge PRs from the command line

In the past releases it was quite frequent around the Feature Freeze date that we ended up with a broken main branch that either did not compile or there were failing tests. It was often due to concurrent merges to the main branch via the "Rebase and merge" button. To overcome the problem we would like to suggest only ever merging PRs from a command line. Thank you Stephan for the idea! The suggested workflow would look as follows:

1. Pull the change and rebase on the current main branch
   
2. Build the project (e.g. from IDE, which should be faster than building entire project from cmd) -> this should ensure the project compiles
3. Run the tests in the module that the change affects -> this should greatly minimize the chances of failling tests
4. Push the change to the main branch

Let us know what you think!

Best,

Guowei & Dawid

Hi, community:

Friendly reminder that today (3.31) is the last day of feature development. Under normal circumstances, you will not be able to submit new features from tomorrow (4.1). Tomorrow we will create 1.13.0-rc0 for testing, welcome to help test together.

After the test is relatively stable, we will cut the release-1.13 branch.

Hi Guowei and Dawid,

I want to request the permission to merge this feature [1], it's a useful improvement to sql client and won't affect 

other components too much. We were plan to merge it yesterday but met some tricky multi-process issue which 

has a very high possibility hanging the tests. It took us a while to find out the root cause and fix it. 

Since it's not too far away from feature freeze and RC0 also not created yet, thus I would like to include this

in 1.13.

Hi Dawid and Guowei,

I'd like to merge [FLINK-13550][rest][ui] Vertex Flame Graph [1]. We are pretty much just waiting for AZP to turn green, it's separate from other components, and it's a super useful feature for Flink users.

Best,

Arvid

Hi all,

@Kurt @Arvid I think it's fine to merge those two, as they are pretty much finished. We can wait for those two before creating the RC0.

@Leonard Personally I'd be ok with 3 more days for that single PR. I find the request reasonable and I second that it's better to have a proper review rather than rush unfinished feature and try to fix it later. Moreover it got broader support. Unless somebody else objects, I think we can merge this PR later and include it in RC1.

Best,

Dawid

Hi All,

I would really love to merge https://github.com/apache/flink/pull/15307 prior to 1.13 release cutoff, it just needs some more tests which I can hopefully get to today / tomorrow morning.

This is a critical fix as now predicate pushdown won't work for any stream which generates a watermark and wants to push down predicates.

Hi, Yuval

Thanks for your contribution. I am not a SQL expert, but it seems to be beneficial to users, and the amount of code is not much and only left is the test. Therefore, I am open to this entry into rc1.
But according to the rules, you still have to see if there are other PMC's objections within 48 hours.
