                 Key: CALCITE-3631
                 URL: https://issues.apache.org/jira/browse/CALCITE-3631
             Project: Calcite
          Issue Type: Sub-task
            Reporter: Shuo Cheng


Calc combines the functionality of Project, and it's created in the later 
stages of optimization.

So it's necessary to make Calc hintable now.
