   My vote for now would be (2), but, why does the console 'group by interval' feature need to do a subquery? What's wrong w/:
   
   ```java
   SELECT COUNT(*), "datasource", "start", "end"
   FROM sys.segments
   WHERE "datasource" = 'wikiticker'
   GROUP BY "datasource", "start", "end"
   ORDER BY "start" DESC
   LIMIT 100
   ```
