Re: Many2many relationships

Thanks, the example helps a lot. Kylin itself does not provide special feature about the many2many relationships as described in the article. Actually the classic workarounds mentioned in the article are good ones and work for Kylin too. In addition, you may make a view of user-join-sport, and

Re: expansion rate so high

Fixed length encoding is the least efficient encoding and a cause of the high expansion. Consider use dictionary, or some custom encoding. On Wed, May 18, 2016 at 12:16 PM, hongbin ma wrote: > I guess there is one or more dimensions with very high cardinality? have > you
