    Description

      This phase happens during cube building. To be able to trigger cube planner, one of the following preconditions should be satisfied.

      • The cube is empty
      • Job is for refreshing the only one segment.

      Since cube planner is based on cuboid row count, if the first segment is empty and there's no useful row count info, cube planner should not be triggered in this phase.

      We also introduce a threshold. If the total number of defined cuboids is less than this threshold, cube planner should not be triggered.
