   ### Search before asking
   
   - [X] I had searched in the 
[issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no 
similar issues.
   
   
   ### Version
   
   1.1.5 
   
   ### What's Wrong?
   
   select
     sum(t1.指标1),
     t1.维度1,
     t1.维度2,
     t1.维度3
   from
     fin_dw.table1 t1
     join fin_dim.table2 t2 on (
     ....
     )
   group by
     t1.维度1,
     t1.维度2,
     t1.维度3
   
   table1数据量10亿左右,table2数据量2.5亿左右,doris优化器选择的join方式是broadcast table2,会导致查询超时。
   
   ### What You Expected?
   
   右表数据量比较大时,不要采用broadcast,要使用shuffle的join方式。
   
   ### How to Reproduce?
   
   _No response_
   
   ### Anything Else?
   
   _No response_
