[GitHub] [flink] sjwiesman opened a new pull request #13178: [FLINK-18977][datastream] Extract WindowOperator construction into a builder class
sjwiesman opened a new pull request #13178:
URL: https://github.com/apache/flink/pull/13178
## What is the purpose of the change
Extracts the logic from WindowedStream into a builder class so that there is one definitive way to create and configure the window operator. This is a pre-requisite to supporting the window operator in the state processor api.
## Verifying this change
This change is a trivial rework / code cleanup without any new test coverage, however, I did execute the end 2 end tests as additional verification.
## 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/Mesos, 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**)
