Which precision (error rate) you selected for this measure? "error rate < 1.22%" will take much more storage than "error rate < 9.75%", user need select proper precision depends on need.
Also, when you state "cuboid size was very large and cast much time", please provide detail information like source data size, dimension number, dimension cardinality, measure definition, your hadoop cluster capacity, cube expansion rate, build time etc. Otherwise we couldn't make judgement and give comment. 2016-03-10 23:20 GMT+08:00 热爱大发挥 <[email protected]>: > In measures step, I try to count distinct cardinality column (like > user_id), then I found the cuboid size was very large and cast much time. > is deprecated count distinct with the high cardinality column??? > -- Best regards, Shaofeng Shi
