Hi devs, When working on the FLIP-406[1], I realized that moving all options of ExecutionCheckpointingOptions(flink-streaming-java) to CheckpointingOptions(flink-core) depends on relocating the enum CheckpointingMode(flink-streaming-java) to flink-core module. However, the CheckpointingMode is annotated as @Public and used by datastream api like 'CheckpointConfig#setCheckpointingMode'. So I'd like to start a discussion on moving the CheckpointingMode to flink-core. It is in a little bit of a hurry if we want the old enum to be entirely removed in Flink 2.x series, since the deprecation should be shipped in the upcoming Flink 1.19. I suggest not creating a dedicated FLIP and treating this as a sub-task of FLIP-406.
I prepared a minimal change of providing new APIs and deprecating the old ones[2], which could be merged to 1.19 if we agree to do so. Looking forward to your thoughts! Also cc RMs of 1.19 about this.
