-----------------------------------
Summary: Add cube-segmentation for base cube
Key: LENS-974
URL: https://issues.apache.org/jira/browse/LENS-974
Project: Apache Lens
Issue Type: New Feature
Reporter: Sushil Mohanty
With cube segmentation a cube can have multiple cubes and all these child cubes
together will make the cube complete.
CubeSegmentation and CubeFactTable will sit together, which means it can
belong to only one base cube. A base cube can have one or more cube
segmentations. Fields of segmentation will be intersection of all columns of
its cubes. Segmentation will have weight to compare with its buddies (facts or
other segmentations). Also it can have start and end time defined or it can
derive from its underline facts.
eg:
base_cube
|_fact1
|_fact2
|_cube_segment1
|_cube1
|_fact_11
|_fact_12
...
...
|_cube_segment2
|_cube2
|_fact_21
|_fact_22
...
...
