Sibling means, the cubiods which have the same number of aggregations; let me give an example:
Assume we have a cube which has 3 dimensions, the base cuboid id will be 111; The base cuboid has 3 children: 110, 101, 011; These three are siblings; Among them, 110 > 101 > 011; 110 and 101 has same children 100; As 101 < 110, so the 100 will be aggregated based on 101, instead of 110; So 100 will be excluded from the children of 110; Hope it helps for you to understand; On 3/11/15, 6:06 PM, "汪浩" <[email protected]> wrote: >hi,all > Does anybody know the meaning of function findSmallerSibling in >CuboidScheduler.java?
