Hi Yujunliang, The timestamp value is not fitting as a dimension, as the granularity is too fine (粒度太细).
Please normalize it to a higher level like Day or Hour, then use that in the dimension. This is a common practice in designing a cube. Here is a good article you can refer to: http://blog.csdn.net/yu616568/article/details/50548967 Hope this helps. 2017-12-18 20:58 GMT+08:00 yujunliang <609417...@qq.com>: > yes, the cube has the big dictionary.So,which encoding a high cardinality > column should use.The column is the time in the format "yyyy-MM-dd HH: mm: > ss".Shaofeng,have you some advice for me? > > -- > Sent from: http://apache-kylin.74782.x6.nabble.com/ > -- Best regards, Shaofeng Shi 史少锋
