> Key: FLINK-23252
> URL: https://issues.apache.org/jira/browse/FLINK-23252
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / State Backends
> Reporter: Roman Khachatryan
> Priority: Major
> Fix For: 1.14.0
>
>
> Currently, recovery from savepoint with changelog.enabled altered is not
> supported (an exception will be thrown because of wrong state handle type).
>
> It can be implemented by: * {{disabled -> enabled}} : load materialized state
> with empty non-materialized
> * {{enabled -> disabled}}: in {{changelog.snapshot()}} , call
> {{underlyingBackend.snapshot()}} (instead of {{writer.persist()}}) if
> savepoint
