--------------------------------------

Hi,  [~kisimple], What's the status of this issue, I have an almost done patch, 
If you don't mind, could I take over this issue?

> Migrate enum serializers to use new serialization compatibility abstractions
> ----------------------------------------------------------------------------
>
>                 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: boshu Zheng
>            Priority: Major
>
> 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.
