-------------------------------
That's good information. Thanks Yanghong!
> Introduce cube planner able to select cost-effective cuboids to be built by
> cost-based algorithms

> Key: KYLIN-2727
> URL: https://issues.apache.org/jira/browse/KYLIN-2727
> Project: Kylin
> Issue Type: New Feature
> Affects Versions: v2.0.0
> Reporter: Zhong Yanghong
> Assignee: Zhong Yanghong
>
> There're several disadvantages to create partial cubes only based on static
> rules:
> * To learn the concept of these rules will bring extra burden to cube admins
> * To achieve a goal cuboid set may need a very complicated set of static rules
> * Cube designers may be not familiar with business related query patterns,
> resulting in few static rules able to applied
> * Static rules created at first may not correct or user query patterns are
> changing dynamically
> The goal of cube planner is to reduce effort for cube admins to design an
> effective partial cube. It owns the following advantages:
> * No sophisticated combination of static rules is needed
> * Allow more dimensions to be included with few static rules
> * Able to adjust a non-cost-effective cuboid set to a cost-effective one
> based on historical queries
