[DISCUSS] Feature Freeze

[Ufuk Celebi-2]

Hey devs! :-)

We decided to follow a time-based release model with the upcoming 1.3
release and the planned feature freeze is on Monday, May 1st.

I wanted to start a discussion to get a quick overview of the current
state of things.

- Is everyone on track and aware of the feature freeze? ;)
- Are there any major features we want in 1.3 that have not been merged yet?
- Do we need to extend the feature freeze, because of an important feature?

Would be great to gather a list of features/PRs that we want in the
1.3 release. This could be a good starting point for the release
manager (@Robert?).

Best,

Ufuk

Hi Ufuk,

Thanks for starting this discussion!

One feature that immediately comes to my mind is incremental checkpointing
given it's production impact.

https://issues.apache.org/jira/browse/FLINK-6364

It would be good to get some better understanding how the implementation
effort is going and whether it is reasonable to expect this to be included
in 1.3.

Regards,
Gyula

The FLINK-6364 <https://issues.apache.org/jira/browse/FLINK-6364> seems
need an accompanying FLIP [1] to help review.

I dont see for this one in the list of existing proposals.

Hi Ufuk,
Thanks for the heads-up.

In terms of table API and SQL, I am hoping we can get the following
features (which have not completed merged yet) included in 1.3:

1. UDAGG (FLINK-5564),  I am working on the last PR (FLINK-5906) to close
this feature.
2. Retract (FLINK-6047), we are planning to merge retract feature-branch to
master-branch after FLINK-6093 is merged.
3. Refactor UDTF interface(FLINK-6334), we are planning to open the PR
today.

I feel we are very close to complete the above features (thanks for all the
reviews from Fabian and Timo). So It would be great if we can extend a few
days to freeze the 1.3.

Thanks,
Shaoxuan

Hi everybody,

from an Table API / SQL point of view, three major features are not
completed yet:
- user-defined aggregation functions: Most of the preparation work is done.
There is one PR missing to actually register and analyze UDAGGs.
- retraction support: This feature was developed in a feature branch
(table-retraction) and is almost complete as well. There is one PR missing
for the conversion of Tables to DataStreams.
- time indicators: Timo is working on this feature and AFAIK, close to
finish it.

I know that the contributors for the UDAGG and retraction support are
working on their last PRs right now.

So, from the Table API / SQL point of view, we are very! close to finish
our efforts.
A few days more time before the feature freeze would help to ensure that
the Table API / SQL makes a huge step forward with Flink 1.3.

Cheers, Fabian
