> Optimize job is for adjusting existing cuboid set. Its data source is base
> cuboid. And it's another input is a set of cuboids recommended by cube
> planner algorithms. By comparing the new recommended cuboids _*R*_ and
> current prebuilt cuboids _*C*_, optimize job will do the following things:
> # Filter the overlap cuboids and remove the ones in _*C*_ but not in _*R*_
> # Update the shard id of the overlap cuboids
> # Add the missing cuboids in _*R*_ but not in _*C*_ with base cuboid as input
> for cubing
