Shaofeng SHI commented on KYLIN-2244: ------------------------------------- Deprecate "kylin.cube.size-estimate-memhungry-ratio" and add new "kylin.cube.size-estimate-countdistinct-ratio" (with default 0.05). When estimate the cuboid size, for count distinct measure (both HLL and Bitmap), use this ration. For dimension and other measure value, use the ordinary "kylin.cube.size-estimate-ratio" (default 0.25). > "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 > Components: Job Engine > Reporter: Shaofeng SHI > Fix For: v1.6.1 > > > 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; -- This message was sent by Atlassian JIRA (v6.3.4#6332)
