Description

In some query case, I find the size of  `isExactlyMatchSet` was bigger than `icuboidIds`i in query log. 

 

For example, there is a join scene like this :

==========================[QUERY]===============================
Query Id: d99bdb35-5d97-b0c0-35a9-db933f3cb64f
SQL: select a.,b. from 
(select SELLER_ID,sum(PRICE)  as PRICE from KYLIN_SALES where PART_DT > '2012-01-01' and  PART_DT < '2012-02-01' GROUP BY SELLER_ID limit 10) a 
left join   KYLIN_ACCOUNT b on a.SELLER_ID = b.ACCOUNT_ID
