             Summary: Changelog backend doesn't apply TTL after recovery
                 Key: FLINK-23277
                 URL: https://issues.apache.org/jira/browse/FLINK-23277
             Project: Flink
          Issue Type: Bug
          Components: Runtime / State Backends
            Reporter: Roman Khachatryan
            Assignee: Roman Khachatryan
             Fix For: 1.14.0


Upon recovery, changelog backend requests states to apply changes.
TTL config is not available at this moment, so states are created regardless of 
TTL config.
One solution is to serialize TTL config along with metadata (in changelog).

Note: values are already serialized as TTL values and serializers as TTL 
seralizers
