Right now we do query planning all in one step, converting a Calcite logical
Rel tree into a Phoenix physical Rel tree.
We'll have to divide this process into two or more stages. The basic two-stage
model will be logical planning and physical planning, where general
optimization rules and the conversion from Calcite logical algebra to Phoenix
logical operators will take place in the logical planning stage, and Phoenix
physical-operator-specific rules will be assigned to the physical planning
stage.
