----------------------------------------
Component/s: Runtime / State Backends
> Support force migration between incompatible state schemas/serializers
> ----------------------------------------------------------------------
>
> Key: FLINK-12045
> URL: https://issues.apache.org/jira/browse/FLINK-12045
> Project: Flink
> Issue Type: Improvement
> Components: API / Type Serialization System, Runtime / State Backends
> Reporter: Yu Li
> Assignee: Yu Li
> Priority: Major
>
> Under certain circumstances user would choose to do force state schema
> migration, for example since we suggest to avoid using Kryo for state
> serialization, user might want to use POJO/Avro serializers instead and wish
> Flink automatically perform a force migration when required to.
> This JIRA targets at supporting such force migration requirements.
