> As mentioned in [PR review of FLINK-10043|https://github.com/apache/flink/pull/7674#discussion_r257630962] 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.
