> If the checkpoint file is used as the initial state of the savepoint startup, 
> it must be ensured that the state backend used before and after is the same 
> type, but in actual production, there will be more and more state, the 
> taskmanager memory is insufficient and the cluster cannot be expanded, and 
> the state backend needs to be switched at this time. And there is a need to 
> ensure data consistency. Unfortunately, currently flink does not provide an 
> elegant way to switch state backend, can the community consider this proposal
