liyang commented on KYLIN-1049:
-------------------------------
This has some synergy with KYLIN-995, at least, the design will be very related.
Not sure the priority of this. Most big data OLAP we see is happy with star
schema, typically transformed from online snowflake schema by a ETL process.
Star schema has obvious advantage in terms of simplicity and performance for
big data. Even more so for streaming analysis cases.
> Support many-to-many relationships and snowflake schemas

> The use case for this is described in this dev mailing list email:
> http://mail-archives.apache.org/mod_mbox/kylin-dev/201506.mbox/%3CCAOnRbQUoLmPBvSMU-kR4Qq%3DRs4-SZcUgT6xZ2ksDbWtjHSB6gg%40mail.gmail.com%3E
> The proposed solutions in that email thread do not work, because they only
> work if the data model has one many-to-many lookup table. Our data model has
> several of them.
