> Add key serializer's config snapshot to KeyedBackendSerializationProxy

> Key: FLINK-6600
> URL: https://issues.apache.org/jira/browse/FLINK-6600
> Project: Flink
> Issue Type: Improvement
> Components: State Backends, Checkpointing
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
> Fix For: 1.3.0, 1.4.0
>
>
> Currently, only the key serializer is included in what's written for a keyed
> state backend in checkpoints. The namespace and state serializer already have
> their config snapshots included in the individual registered state's metainfo.
> We should also include the configuration snapshot of the key serializer in
> {{KeyedBackendSerializationProxy}} so that we can also be flexible in
> allowing migration / transformation of the key in the future.
