The main idea is that a scientist writing algebraic expressions cannot care less of distributed operation plans and works entirely on the logical level just like he or she would do with R. -Another point of logical level manipulations is decoupling computation from distributed back-end. -That is, the algebraic optimizer also acts as a translation layer to a concrete machine cluster computational back-end. -Although it is not currently on roadmap (and not even 100% decoupled on the API level), -one can think of bringing in other back-ends and have the same algorithms running on those without -a change. +Another idea is decoupling logical expression from distributed back-end.
