------------------------------------------
Summary: 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
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.
