------------------------------------

             Summary: Introduce a resolved expression with data type
                 Key: FLINK-12899
                 URL: https://issues.apache.org/jira/browse/FLINK-12899
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / API
            Reporter: Timo Walther
            Assignee: Timo Walther


In order to move the \{{OperationTreeBuilder}} and expression resolver rules to the \{{flink-table-api-java}} module, we need to distinguish between general expression and resolved expressions. All resolved expressions have a output data type and are potentially serializable.
