>                 Key: CALCITE-544
>                 URL: https://issues.apache.org/jira/browse/CALCITE-544
>             Project: Calcite
>          Issue Type: Sub-task

> Interpreter can handle scan, filter, project, values and (with CALCITE-543) aggregate. This task would add union.
> You probably need to add a method {{public void visit(Union union)}} to {{CoreCompiler}}. Add tests to InterpreterTest for union and union all. 
> This is a good task for a beginner (as evidenced by the "newbie" label).
