回复：[DISCUSS] Feature Freeze

[wangzhijiang]

Hi Ufuk,
Thank you for launching this topic!
I wish my latest refinement of buffer provider (https://issues.apache.org/jira/browse/FLINK-6337)  to be included in 1.3 and most of the jobs can get benefit from it. And I think it can be completed with the help of your reviews this week.

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

Hello,

FLINK-5892 (Restoring state by operator) is also nearing completion, but
with only 1 day left before the weekend we're cutting it really short.

Since this eliminates a major pain point when updating jobs, as it
allows the modification of chains, another day or 2 would be good i think.

Regards,
Chesnay

Hi Ufuk

Incremental checkpointing can significantly improve the performance of checkpointing.
I hope it can be included in release 1.3.

I am working with Stefan on the last subtask, which attempts to implement incremental checkpointing in RocksDB state backend (FLINK-6364).
Without future optimizations, the work is near completion. So i think 2-3 more days would be good.

Regards
Xiaogang

Hello,

Thanks for starting this thread. It would be great to see the following
features available in Flink 1.3:

* Support for complex schema: FLINK-6033, FLINK-6377
* Various improvements on SQL over group windows: FLINK-6335, FLINK-6373
* StreamTableSink for JDBC and Cassandra: FLINK-6281, FLINK-6225
* Decoupling Flink and Hadoop: FLINK-5998

All of them have gone through at least one round of review so I'm
optimistic that they can make it to 1.3 in a day or two.

Additionally it would be great to see FLINK-6232 go in, but it depends on
FLINK-5884 so it might be a little bit tough.

Regards,
Haohui

Hi Devs,

Thanks for the release plan.

Could you also please add the feature FLINK-6196 Support dynamic schema in Table Function?

I’d like to update the code as comments left on PR today.

I will try to make sure the code is updated before the Apr 30th.

Thanks,

Zhuoluo 😀

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

If it's not a problem it will be great for us to include also FLINK-6398
<https://issues.apache.org/jira/browse/FLINK-6938> if it's not a big deal

Best,
Flavio

I think there might be a typo. We haven’t yet reached issue number 6389, if I’m not mistaken. The latest as I’m writing this is 6410.

Sorry, you're right Aljosha..the issue number is correct, the link is
wrong! The correct one is https://issues.apache.org/jira/browse/FLINK-6398

Any chance to cherry-pick this also into 1.2.1? We're usign Flink 1.2.0 in
production and maybe an upgrade to 1.2.1 would be a safer option in the
short term..

Flavio

FLINK-5892 has been merged.

For FLINK-4545 (replacing numNetworkBuffer parameter) a PR is also still
open and could use a second pair of eyes.

Hi,

I have 2 parts to discuss about delaying the feature freeze for a bit:

1. Allow upgrades to state serializers (FLINK-6178)
The feature is split up into 2 PRs, one of which is already open and the second one coming up very soon.
PR #1 reconfigurable TypeSerializers: https://github.com/apache/flink/pull/3804
PR #2 (will open soon) integrate serializer reconfiguration into state restore flow (FLINK-6425)

2. Major new functionality for the Kafka and Kinesis consumers.
Kafka - partition & topic regex discovery (PR - https://github.com/apache/flink/pull/3746)
Kinesis - rescalable Kinesis consumer (PR - https://github.com/apache/flink/pull/3001)

All above mentioned features are not yet merged to master. I think an additional few days to the end of this week for the feature freeze should make this possible.

Cheers,
Gordon

[Stephan Ewen]

Thanks all for the lively discussion about the feature freeze and how to
proceed.
Because we committed to a time-based release schedule, we should not break
the feature freeze too badly, or we would just disable the
time-based-release-policy at the very first time it would trigger.

Here are a few thoughts about what we can do:

  - First of all, please note that feature freeze does not mean bug fix
freeze. Important bug fixes can and should go in as part of the 1.3.0
release testing period

  - We should probably not add brand new features to the list at this point
(that would most likely break the release schedule completely)

  - I think there is a case to include some features which are partially
(but not fully) in master already, or exist basically completely as Pull
Requests at this time.

How about we do *freeze the set of features* for the release today, but *leave
a grace period to get the complete-but-not-merged features in until the end
of this week*?
That would mean forking the release-1.3 branch end of this week.


We should try and agree on which features fall under that list, and make
sure each one has a committer committed to merging them in the next days.

[Robert Metzger]

Thanks a lot Ufuk for starting the discussion regarding the 1.3 feature
freeze.

I didn't feature freeze yesterday (Monday) because it was a public holiday
here in Germany.

I haven't made up my mind whether to do the feature freeze today or not.
Many important features seem to be close to completion.
I don't think we can pick features and wait with the release until they are
finished. The only thing I can imagine we could do is extend the deadline a
little bit to give people more time to complete.
But I'm strictly against multiple extensions.

To make the discussion a bit easier, I've collected all the JIRAs mentioned
in this thread. I decided to group them into "really important" and
"important". I hope nobody is offended by my selection and I'm very open to
discuss it.
It doesn't really matter anyways because we will not block the release on
the completion of certain features.


Completed Features for 1.3
- TODO!

Blockers:
- TODO!


Really important (open):
- FLINK-6364: Implement incremental checkpointing in RocksDBStateBackend
(pending PR)
- FLINK-5906: Add support to register user defined aggregates in
TableEnvironment (no PR)
- FLINK-6047: Add support for Retraction in Table API / SQL (depends on
FLINK-6093)
- FLINK-6093: Implement and turn on retraction for table sink (pending PR)
- FLINK-6334: Refactoring UDTF interface (pending PR, under review)
- FLINK-5998: Un-fat Hadoop from Flink fat jar (pending PR, under review)
- FLINK-4545: Flink automatically manages TM network buffer (pending PR,
under review)
- FLINK-6178: Allow upgrades to state serializers (pending PR, no review )


Really important (closed):
- FLINK-5892: Recover job state at the granularity of operator (merged)



Important (open):
- FLINK-6013: Add Datadog HTTP metrics reporter (pending PR, under review)
- FLINK-6337: Remove the buffer provider from PartitionRequestServerHandler
(pending PR, under review)
- FLINK-6033: Support UNNEST query in the stream SQL API (no PR)
- FLINK-6335: Parse DISTINCT over grouped window in stream SQL (pending PR)
- FLINK-6373: Add runtime support for distinct aggregation over grouped
windows (pending PR, under review)
- FLINK-6281: Create TableSink for JDBC (pending PR, under review)
- FLINK-6225: Support Row Stream for CassandraSink (pending PR, under
review)
- FLINK-6196: Support dynamic schema in Table Function (pending PR, under
review)
- FLINK-4022: Partition and topic discovery for FlinkKafkaConsumer (pending
PR, no review)
- FLINK-4821: Implement rescalable non-partitioned state for Kinesis
Connector (pending PR, under review)
Important (closed):
- FLINK-6377: Support map types in the Table / SQL API (merged)
- FLINK-6398: RowSerializer's duplicate should always return a new instance
(merged)


I'll now collect the list of finished features in 1.3 and the blockers and
update above list.

Stephan's email just came in, and I like the idea of freezing the feature
set now but extending the deadline to Friday for the branching. (Friday 3pm
CEST)

Does everybody agree to that proposal?

[Kostas Kloudas]

The only thing that I want to add in the features to be added for 1.3
is the NOT pattern for the CEP library.

There is an open PR here: https://github.com/apache/flink/pull/3798 <https://github.com/apache/flink/pull/3798>
which is not far from getting in.

Robert, I'd like to see FLINK-5974
<https://issues.apache.org/jira/browse/FLINK-5974> (Mesos DNS support)
added to the list of important issues.  A PR is ready.

[Aljoscha Krettek-2]

This is the list of blocking issues for Flink 1.3: https://issues.apache.org/jira/browse/FLINK-5740?jql=project%20%3D%20FLINK%20AND%20status%20in%20(Open%2C%20%22In%20Progress%22%2C%20Reopened)%20AND%20priority%20%3D%20Blocker%20AND%20fixVersion%20%3D%201.3.0 <https://issues.apache.org/jira/browse/FLINK-5740?jql=project%20=%20FLINK%20AND%20status%20in%20(Open,%20%22In%20Progress%22,%20Reopened)%20AND%20priority%20=%20Blocker%20AND%20fixVersion%20=%201.3.0>

Could everyone please update the state of the issues mentioned in this thread to “blocking” and set the version to “1.3.0” if they feel that this is appropriate. Otherwise it is very hard for the release manager to get an overview over the progress of the release. With an up-to-date list it’s also possible to triage issues and discuss on the issue whether it really should be a release blocker.

Best,
Aljoscha
