[GitHub] [flink] dawidwys opened a new pull request #16557: [FLINK-23460] Add a global flag for enabling/disabling final checkpoints
dawidwys opened a new pull request #16557:
URL: https://github.com/apache/flink/pull/16557
## What is the purpose of the change
We should have a feature toggle for enabling/disabling checkpoints after tasks finished. The final checkpoint will be a new feature so users should have an option to fallback to the old behaviour if necessary.
## Verifying this change
All existing tests should pass when configured via the feature flag
## Does this pull request potentially affect one of the following parts:
- Dependencies (does it add or upgrade a dependency): (yes / **no**)
- The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (**yes** / no)
- The serializers: (yes / **no** / don't know)
- The runtime per-record code paths (performance sensitive): (yes / **no** / don't know)
- Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: (**yes** / no / don't know)
- The S3 file system connector: (yes / **no** / don't know)
## Documentation
- Does this pull request introduce a new feature? (yes / **no**)
- If yes, how is the feature documented? (not applicable / docs / **JavaDocs** / not documented)
