>
> Currently, only the key serializer is included in what's written for a keyed
> state's metainfo in checkpoints. The namespace and state serializer already
> have their config snapshots included in the metainfo.
> We should also include the configuration snapshot of the key serializer in
> there so that we can also be flexible in allowing migration / transformation
> of the key in the future.
