    Description

      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.
