Summary: "kylin.job.cuboid.size.memhungry.ratio" shouldn't be
applied on measures like TopN
Key: KYLIN-2244
URL: https://issues.apache.org/jira/browse/KYLIN-2244
Project: Kylin
Issue Type: Improvement
Reporter: Shaofeng SHI
The parameter "kylin.job.cuboid.size.memhungry.ratio" (new name "
kylin.cube.size-estimate-memhungry-ratio") default value 0.05, is based on the
compression ration on HyperLogLog; it doesn't fit for other memory hungry
measures like TopN, Raw, etc;
