Hi Yanwei, 1: Kylin doesn't directly support snowflake schema; If you want to build cube for such a model, you can firstly create a flat Hive View over those tables, and then use the view as the fact table in Kylin;
2. "join" here means "inner join" I think; "inner join" will filter the records that doesn't match with the PK in lookup table, I belive you know its difference with "left join". 2016-06-20 17:53 GMT+08:00 李寅威 <251469...@qq.com>: > Hi all: > > > I have two questions as follows: > > > 1.Can kylin support snowflake schema in data warehouse? > 2.If Kylin can only support star schema, under what circumstances shall > we use join instead of left join? > > > look forward to your help, thx~ > > > > > > > ------------------ > 李寅威 | CVTE > cor...@foxmail.com > 广州视源电子科技股份有限公司 > Guangzhou Shiyuan Electronics Co., Ltd. -- Best regards, Shaofeng Shi
