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

             Summary: Changelog backend creates "raw materialized" savepoint but expects it's "normal" snapshot on recovery
                 Key: FLINK-23278
                 URL: https://issues.apache.org/jira/browse/FLINK-23278
             Project: Flink
          Issue Type: Bug
          Components: Runtime / State Backends
    Affects Versions: 1.14.0
            Reporter: Roman Khachatryan
            Assignee: Roman Khachatryan
             Fix For: 1.14.0


Savepoint consist of "raw" keyed handles from the underlying backend:
{code}
    public SavepointResources<K> savepoint() throws Exception {
        return keyedStateBackend.savepoint();
    }
{code}

On recovery, ChangelogStateBackendHandles are expected.

This fails e.g. SavepointWriterITCase if enabled.
