Re: some confuse about Mandatory Dimensions

[Billy(Yiming) Liu]

If you set A, B, and C as mandatory dimensions, that means Kylin will save
the cuboid result by grouping A, B, C internally. But that not means you
could only query by grouping A, B, C.  If you only query A, B. The final
result will do post-aggregation by grouping the above cuboid. Same as query
grouping A. The cost is performance, since more post-aggregation needed.
But if you query by grouping D. There would be no result, since you missed
the mandatory dimension.

[jira] [Created] (KYLIN-2202) Fix the conflict between KYLIN-1851 and KYLIN-2135

 Summary: Fix the conflict between KYLIN-1851 and KYLIN-2135
 Key: KYLIN-2202
 URL: https://issues.apache.org/jira/browse/KYLIN-2202
 Project: Kylin
  Issue Type: Bug
Affects Versions: v1.5.4.1
Reporter: XIE FAN
 Fix For: Future


In KYLIN-1851, we use a new dictionary(TrieDictionaryForest) to reduce the peek 
memory usage of the dictionary building procedure. In order to use the new 
dictionary, we need to make sure that the input data is sorted. But in 
KYLIN-2135, the output data is split into multi files and values in different 
files may be out-of-order. So we need to fix the conflict between this two 
issues.
