             Summary: Add Shuffle Node
                 Key: CALCITE-594
                 URL: https://issues.apache.org/jira/browse/CALCITE-594
             Project: Calcite
          Issue Type: New Feature
            Reporter: Ashutosh Chauhan
            Assignee: Ashutosh Chauhan


Calcite is increasingly targeting to support distributed execution engines. Any 
distributed sql engine has Shuffle/Exchange operator to shuffle their data with 
other deamons in the runtime system. It will be useful to add a notion of 
{{Shuffle}} RelNode as a first class citizen in Calcite.
