zhijiangW opened a new pull request #7963: [FLINK-11885][network] Introduce RecordWriterBuilder for creating RecordWriter instance URL: https://github.com/apache/flink/pull/7963 ## What is the purpose of the change The current `RecordWriter` would be refactored as an abstract class for improving broadcast mode mentioned in FLINK-10995. So it is better to migrate the logic of building `RecordWriter` instance into a separate `RecordWriterBuilder` utility class which should be the only entrance for other usages. ## Brief change log - *Introduce new `RecordWriterBuilder` class for providing static creation methods* - *Remove useless constructor in `RecordWriter`* - *Make constructor package private for `BroadcastRecordWriter`* - *Change other usages of creating `RecordWriter` via new builder class* ## Verifying this change This change is already covered by existing tests, such as *RecordWriterTest*. ## 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, 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?
