                 Key: FLINK-12559
                 URL: https://issues.apache.org/jira/browse/FLINK-12559

            Assignee: godfrey he


In [FLINK-11822|https://issues.apache.org/jira/browse/FLINK-11822], we have introduced all Flink metadata handlers,  several {{RelNode}}s (e.g. window aggregate) have not be implemented. So this issue aims to introduce metadata handlers on window aggregate.
