Hi,all
I have create a cube in My System with Mandatory Dimensions such as A
B C, and the Measure use count distinct filed “u” will HLL ,
When the segment of the cube complete,I query the result with kylin sql as
“select count(distinct u) from table where A=xxx and b=yyy” or “select
count(distinct u) from table where A=xxx ”. The result is correct
In my opinion, all of the query condition must be set (A=xxx,B=yyyy,C=zzz) ,the
kylin sql can be wrok,
The question is How the Kylin query the result and the distinct value is right
? that is unbelievable
