   > The only way to do this at the moment is by using views as a datasource 
(where the view is making the join). We understand that there's performance 
impacts and in general we recommend denormalizing/materializing.
   > 
   > We may add support for joins in the future, where you could define 
many-to-one relationship to dimension tables (in the datasource editor) and 
define the join criteria there. Then the columns coming from these tables would 
show up under the "columns" tab. Presumably the SQL-generation logic would only 
join as needed.
   
   So what's the plan?
