[jira] [Created] (FLINK-24054) Let SinkUpsertMaterializer emit +U instead of only +I

Timo Walther created FLINK-24054:
------------------------------------

             Summary: Let SinkUpsertMaterializer emit +U instead of only +I
                 Key: FLINK-24054
                 URL: https://issues.apache.org/jira/browse/FLINK-24054
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Runtime
            Reporter: Timo Walther
            Assignee: Timo Walther


Currently, {{SinkUpsertMaterializer}} is not able to emit +U's but will always emit +I's. Thus, resulting changelogs are incorrect strictly speaking and only valid when treating +U and +I as similar changes in downstream operators.
