> CheckpointCoordinatorConfiguration#isExactlyOnce() is inconsistent with
> StreamConfig#getCheckpointMode() when checkpoint is disabled.
> CheckpointCoordinatorConfiguration#isExactlyOnce() returns true if checkpoint
> mode is EXACTLY_ONCE mode and return false if checkpoint mode is
> AT_LEAST_ONCE while StreamConfig#getCheckpointMode() will always return
> AT_LEAST_ONCE which means always not exactly once.
