However, there is a significant blocker to implement the proposed solution. Currently, the non-ConfigOption objects in the StreamExecutionEnvironment, CheckpointConfig, and ExecutionConfig have already been exposed to users through the public API. This poses a challenge when trying to modify the existing implementation to accommodate the proposed solution. Therefore, this FLIP aims to deprecate these Java objects and their corresponding getter/setter interfaces, ultimately removing them in FLINK-2.0.
Please note that this FLIP does not include deprecating fields related to serialization. The deprecation work for the serialization part will be carried out in conjunction with the relevant work in the FLINKPlease note that this FLIP does not include deprecating fields related to serialization.

Deprecate following classes, fields and methods

Suggested alternative: Users can configure the RestartStrategyOptions related ConfigOptions, such as "Users can configure the RestartStrategyOptions related ConfigOptions, such as "restart-restart-strategy.type", in the configuration, instead of passing a RestartStrategyConfiguration objectin the configuration, instead of passing a RestartStrategyConfiguration object.

Suggested alternative: Users can configure "state.checkpoint-storage" in the configuration as the fully qualified name of the checkpoint storage or use some FLINK-provided checkpoint storage shortcut names such as "jobmanager" and "filesystem", and provide the necessary configuration options for building that storage, instead of passing a CheckpointStorage objectand provide the necessary configuration options for building that storage, instead of passing a CheckpointStorage object.
