lichenglin updated SPARK-13907:
-------------------------------
Description:
I tried to build a cube on a 100 million data set.
When I set 9 fields to build the cube with 10 cores.
It nearly coast me a whole day to finish the job.
At the same time, it generate almost 1”TB“ data in the "/tmp“ folder.
Could we refer to the ”fast cube“ algorithm in apache Kylin
To make the cube builder more quickly???

For example
group(A,B,C)'s result can be create by the groupdata(A,B)
