Zhong Yanghong commented on KYLIN-3351:
---------------------------------------

Hi [~praveenece],

there're two phases for cube planner. The first phase was triggered at the first building
for a cube. In this phase, statistics is not needed. However, the second phase is cost-based
which mainly depends on the collected statistics. In this phase, we can do optimization to
adjust the current built cuboids and define the cuboids for future building.

For more details, please refer [KYLIN-2727]
