The date format on "Data model" page is mainly for generating the HQL for pulling data from hive. For a stream cube, the "MINUTE_START", "HOUR_START" (and other derived date columns) are transformed by Kylin to standard "timestamp" type; Then the date format on "Data model" page is useless in this case. 2016-11-21 11:07 GMT+08:00 仇同心 <[email protected]<mailto:[email protected]>>: Hi ,all In this article at http://kylin.apache.org/docs16/tutorial/cube_streaming.html, I have learned that Streaming Cube must be partitioned; If you’re going to build the Cube incrementally at minutes level, select “MINUTE_START” as the cube’s partition date column. If at hours level, select “HOUR_START”. In the Setting page of Model of the Designer, I have a little confused: “Date Format” and “Has a separate "time of the day" column” , these two options is useless? Because when the model has been edited, “Partition Date Column” can only be edited. Thanks! -- Best regards, Shaofeng Shi 史少锋
