[jira] [Created] (CALCITE-558) Replace ENUMERABLE with new default convention, INTERPRETABLE

Julian Hyde created CALCITE-558:
-----------------------------------

             Summary: Replace ENUMERABLE with new default convention, INTERPRETABLE 
                 Key: CALCITE-558
                 URL: https://issues.apache.org/jira/browse/CALCITE-558
             Project: Calcite
          Issue Type: Bug
            Reporter: Julian Hyde
            Assignee: Julian Hyde


The default convention is currently ENUMERABLE, which means that to execute a query, and in particular to use the JDBC driver, RelNodes need to be able to convert themselves to code. This introduces a lot of dependencies that make CALCITE-466 difficult to solve.

We propose to add a new convention that can be more easily implemented by a RelNode, using an interpreter or otherwise.
