yuzhang qiu commented on KYLIN-3453:
------------------------------------
Yes, I got that. So why the "create hbase table" step need done so early before
"convert cuboid data to HFile"? Build Cuboid will use some info from the
"create table" step?? Use for RowkeyEncoder?
> Improve cube size estimation for TOPN, COUNT DISTINCT

> Currently, Kylin has poor cube size estimation for TOPN, COUNT DISTINCT. We
> should improve it, then we can get a reasonable split num when cube building.
