Everyone can join as a silent listener.

Timeline

Feature Freeze
(warning) Monday, 16th of August, end of business CEST.
(has been moved in the bi-weekly on the 20th of July)

Release
Mid September

Highlight features

  • ML
  • Table API (Sources, Sink, Schema Inference)
  • Common source metrics (for new sources)

please feel free to add/suggest.

Features

List of features announced by contributors and committers that are likely to be ready for the feature freeze:n

NOTICE: It's preferred 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. 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.

7 Comments

  1. Johannes Moser

    Bi-weekly 8th of June

    Time Plan:

    • Users seem to extend release duration
    • Biased by Users who have their own fork
    • Vanilla Flink Users are not heard (yet)
    • Maybe we should create less pain for users to upgrade in general

    Build stability:

    • 187 issues
    • What can we do to reduce the test instabilities (last release cycle tens of issues, currently ~200, nightly has not been stable for a long time)
    • What is the pattern? (a lot of time outs, a lot of failures in tests)
    • Push to get the number down in the next two weeks > Release managers try to get assignees on the instabilities
    • Teams monitor components (e.g. as part weekly backlog grooming) > React swiftly when new things are reported

    Documentation & Release advertising


    Further topcis

    • Freeze for feature list (maybe in two weeks in the next bi-weekly)


  2. Johannes Moser

    Discussed topics:

    Release Blockers

    Test instabilities

    Time plan

    • The group agreed to keep it as it is.
    • Johannes Moser will distill relevant information from the thread and update the mailing list.

    Criteria for merging PRs

    • Forbid merging with unrelated CI failures
    • Raise importance of docker cache to re-inforce this.

    Dependencies

    • Have a look at the outdated ones within your components.



  3. Johannes Moser

    Bi-weekly 20th of July

    2 weeks left before feature freeze
    do we want to postpone it? when do we want to have the actual freeze?

    • Dong Lin Feedback for FLIP 173, wondering if someone else has any comments.
      Will be added to the Flink ML repo, isn't affected by the feature freeze.
      Johannes Moser , tries to get someone to give feedback.
    • Piotr Nowojski , small hick-up with FLIP-147. needs to implement some smaller things.
      1 or 2 weeks would help, isn't required to delay the feature, hard to say how much this would increase the chance to get it into 1.14, anything else.
    • Timo Walther , FLIP-163, could work in two weeks, having another week would be a safer option. Vacation get review capacity.


    Team updates:

    • Piotr Nowojski
      • Buffer adjustment, voting in this week. Implementation has started. Could be freezed to have more resources for FLIP-147
      • General incremental checkpoints, nor sure if it will be done
      • Support clarified after discussion today
    • Xintong Song
      • Fine Grained would be fine
      • GCS won't happen in 1.14
    • Yun Gao
      • FLIP-147 like Piotr said
      • Scheduler performance for large scale jobs
    • Yun Tang
      • Might need more time to figure out stuff for RocksDB
      • Discussion with Till start today
    • Martijn Visser
      • KafkaSink expected to be done for 1.14
      • Draft PR for Connector Metrics
    • Jark Wu
      • Hive Remaining for 1.14.
      • ALTER TABLE might not make it
      • SQL Client, remaining task is a small effort, next week done
      • Java Code Splitter, two subtasks remaining
      • TVF actively working on that.
      • Serialization and Deserialization merged next week.
    • Jiangjie Qin
      • Workaround for CDC rejecting checkpoint can be removed
      • Unified testing framework, will be missing 1.14.
    • Timo Walther
      • FLIP-129 might be tough,
      • Remaining things tight but doable.
    • Dian Fu
      • Joe will reach out


    Build Stability

    • nightly runs started passing! or failing with 1/2 failures, which is a nice change
    • Green build for nightly runs
    • FLINK-22198 - Getting issue details... STATUS  - Johannes Moser  tries to find someone for this ticket


    What are the highlight features/improvements?

    • Meetup in early August by Xintong.
    • Joe add a section to this page.
    • Ideas
      • ML
      • Table API (Sources, Sink, Schema Inference)
      • Log based checkpoints (although in danger)
        • Time critical tasks are planned
        • Extra time would be also helpful here
      • Maybe shift more resources to FLIP-183
    • Push feature freeze to around 17th of August
