                 Key: FLINK-11449
                 URL: https://issues.apache.org/jira/browse/FLINK-11449
             Project: Flink
          Issue Type: New Feature
          Components: Table API & SQL
            Reporter: Timo Walther


A more detailed description can be found in [FLIP-32|https://cwiki.apache.org/confluence/display/FLINK/FLIP-32%3A+Restructure+flink-table+for+future+contributions].

Calcite will not be part of any API module anymore. Therefore, RexNode translation must happen in a different layer. This issue will require a new design document.
