Jingsong Lee created FLINK-31213:
------------------------------------

             Summary: Aggregation merge engine supports retract inputs
                 Key: FLINK-31213
                 URL: https://issues.apache.org/jira/browse/FLINK-31213
             Project: Flink
          Issue Type: Improvement
          Components: Table Store
            Reporter: Jingsong Lee
            Assignee: Jingsong Lee
             Fix For: table-store-0.4.0


For sum, it can support retracts.
For others, which do not support retraction (`UPDATE_BEFORE` and `DELETE`). If the user allow some functions to ignore retraction messages, the user can configure: `'fields.${field_name}.ignore-retract'='true'`.
