>
> Add an interpreter that can evaluate logical RelNodes (such as FilterRel, TableAccessRel).
> The motivation is similar to OPTIQ-107 but this feature request would interpret logical RelNodes, not RelNodes that implement EnumerableRel. This case would eliminate planning time as well as the janino step.
> We should explicit sources, sinks and start/run/stop methods. A bit less efficient, but gives us the opportunity for detailed tracing and even single-stepping.
> Put code in a new package net.hydromatic.optiq.impl.interpreter.
