> with Stefan and offline discussion with Gordon, after the refactoring work
> serializer passed to {{RocksDBKeyedStateBackend}} constructor is a final one,
> thus the {{StateSerializerProvider}} field is no longer needed.
> For {{HeapKeyedStateBackend}}, the only thing stops us to pass a final
> serializer is the circle dependency between the backend and
> {{HeapRestoreOperation}}, and we aim to decouple them by introducing a new
> {{HeapInternalKeyContext}} as the bridge. More details please refer to the
> coming PR.
