WeiZhong94 opened a new pull request #11448: [FLINK-16666][python][table] Support new Python dependency configuration options in flink-java, flink-streaming-java and flink-table. URL: https://github.com/apache/flink/pull/11448 ## What is the purpose of the change *This pull request adds basic support for the proposed Python Dependency configuration options in `flink-java`, `flink-streaming-java` and `flink-table`. The python dependencies will be registered to distributed cache while the `configure()` method of `ExecutionEnvironment`/`StreamExecutionEnvironment` is called. The metadata of Python dependencies will be transfer to TableConfig and convert to PythonConfig when translating the Python UDF RelNode to Python UDF Operator. * ## Brief change log - *Move `PythonOptions` to `flink-core`.* - *Define the new Python Dependency configuration options in `PythonOptions`.* - *Add `PythonDependencyManager` and use it to process the Python Dependency configuration options while the `configure()` method of `ExecutionEnvironment`/`StreamExecutionEnvironment` is called.* - *Change access level of the `StreamExecutionEnvironment#getConfiguration()` method from `protected` to `public` and add `@Internal` annotation.* - *Transfer the metadata of Python dependencies from the configuration of the `ExecutionEnvironment`/`StreamExecutionEnvironment` to TableConfig before translating the Table API job.* ## Verifying this change This change is already covered by existing tests, such as *PythonOptionsTest*, *PythonDependencyManagerTest*. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (no) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no) - The serializers: (no) - The runtime per-record code paths (performance sensitive): (no) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn/Mesos, ZooKeeper: (no) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature? (yes) - If yes, how is the feature documented? (docs)
