> 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
