Shall we define the base cuboid?
As in the article
http://kylin.apache.org/blog/2016/02/18/new-aggregation-group/ , two aggs
are defined in the last. The AGG1 is base cuboid, shall we define it
explicity? It seems the base cuboid is computed implicit
Re: Shall we define the base cuboid?
Posted by 杨浩 <ya...@gmail.com>.
As in the demo cube "kylin_sales_cube", there are 18 dimensions and one agg
with 15 dimensions. From executing "bin/kylin.sh
org.apache.kylin.engine.mr.common.CubeStatsReader kylin_sales_cube", the
base cuboid is also calated.

Don't think so. With only AGG2, the combination of [cal_dt, city, buyer_id]
is not computed at all.

So, shall we change the document to delete the AGG1 , and says it is
computed by default?

Yes, the base cuboid is the cuboid of all dimensions on rowkey. It is the
parent of all AGG.
