> Key: FLINK-11334
> URL: https://issues.apache.org/jira/browse/FLINK-11334
> Project: Flink
> Issue Type: Sub-task
> Components: State Backends, Checkpointing, Type Serialization System
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Congxian Qiu(klion26)
> Priority: Major
> Labels: pull-request-available
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> This subtask covers migration of:
> * EnumSerializerConfigSnapshot
> * ScalaEnumSerializerConfigSnapshot
> to use the new serialization compatibility APIs ({{TypeSerializerSnapshot}}
> and {{TypeSerializerSchemaCompatibility).
> The enum serializer snapshots should be implemented so that on restore the
> order of Enum constants can be reordered (a case for serializer
> reconfiguration), as well as adding new Enum constants.
> Serializers are only considered to have completed migration according to the
> defined list of things to check in FLINK-11327.
