[jira] [Created] (KYLIN-1049) Support many-to-many relationships and snowflake schemas

Tero Paananen created KYLIN-1049:
------------------------------------

             Summary: Support many-to-many relationships and snowflake schemas
                 Key: KYLIN-1049
                 URL: https://issues.apache.org/jira/browse/KYLIN-1049
             Project: Kylin
          Issue Type: Improvement
            Reporter: Tero Paananen


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.
