> Inject TaskStateRegistry added in FLINK-23139 into existing state backends and use it there to manage private state.
>  
> *Should only take effect if changelog.enabled = true.*
>  
> *Related task*: prevent RocksDB from re-uploading state if checkpoints weren't confirmed (or were aborted).
> (see also FLINK-23461)
> Please implement or create a seperate ticket.
>  
> An alternative solution that was considered is to analyze the returned snapshot for state to manage.
