> Cube Planner used for recommending effective cuboids is based on cost-based algorithm. The aggregated row count plays an important role of the rollup cost from target cuboid to source cuboid. Thus we need to separate filter row count & aggregated row count.
> *One important thing is that coprocessor redeployment needs to be done after this change*
