WeiZhong94 opened a new pull request #8681: [FLINK-12585][python] Align Stream/BatchTableEnvironment with JAVA Table API URL: https://github.com/apache/flink/pull/8681 ## What is the purpose of the change This pull request add `StreamExecutionEnvironment` and `ExecutionEnvironment` for Python Table API so that the usage of Python Table API can align with Java Table API. All APIs used for configuration in `StreamExecutionEnvironment` and `ExecutionEnvironment` have been added. The transitive dependent classes are involved to Python API too, which contains: `ExecutionConfig`, `CheckpointConfig`, `ExternalizedCheckpointCleanup`, `CheckpointingMode`, `ExecutionMode`, `InputDependencyConstraint`, `RestartStrategies`, `StateBackend`, `MemoryStateBackend`, `FsStateBackend`, `RocksDBStateBackend`, `CustomStateBackend`, `PredefinedOptions` and `TimeCharacteristic`. ## Brief change log - *Add `StreamExecutionEnvironment` and `ExecutionEnvironment`.* - *Move execute() method from TableEnvironment to ExecutionEnvironment/StreamExecutionEnvironment.* - *Refactor TableConfig align to Java TableConfig.* - *Add `ExecutionConfig` and relevant APIs.* - *Add `CheckpointConfig` and relevant APIs.* - *Add `StateBackend` and relevant APIs.* ## Verifying this change This change added integration tests in `test_execution_environment.py`, `test_stream_execution_environment.py`, `test_execution_config.py`, `test_check_point_config.py`, `test_state_backend.py`. ## 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, 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? (python docs)
