--------------------------------
Summary: Correct the logic to materizate on wrapped changelog state
Key: FLINK-25465
URL: https://issues.apache.org/jira/browse/FLINK-25465
Project: Flink
Issue Type: Bug
Components: Runtime / State Backends
Reporter: Yun Tang
Assignee: Yun Tang
Fix For: 1.15.0
{{ChangelogKeyedStateBackend#keyValueStatesByName}} would store wrapped state,
such as TTL state or latency tracking state. It will throw exception on
initMaterialization if wrapped:
{code:java}
for (InternalKvState<K, ?, ?> changelogState : keyValueStatesByName.values()) {
checkState(changelogState instanceof ChangelogState);
((ChangelogState) changelogState).resetWritingMetaFlag();
}
{code}
