Zhong Yanghong updated KYLIN-2727: ---------------------------------- Affects Version/s: (was: v2.1.0) > 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 > Reporter: Zhong Yanghong > Assignee: Zhong Yanghong > Fix For: v2.3.0 > > > 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 -- This message was sent by Atlassian JIRA (v6.4.14#64029)
