-----------------------------------------
Summary: Support recovery with altered "changelog.enabled" option
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
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
