-----------------------------------

             Summary: Hitting snapshot has a higher priority than answering min/max mesaure with metadata
                 Key: KYLIN-5755
                 URL: https://issues.apache.org/jira/browse/KYLIN-5755
             Project: Kylin
          Issue Type: Improvement
          Components: Query Engine
    Affects Versions: 5.0-beta
            Reporter: pengfei.zhan
            Assignee: pengfei.zhan
             Fix For: 5.0-beta


KYLIN-5578 using metadata to response min/max aggregation queries. When querying only columns on the dimension table, the query result from the snapshot does not match the reuslt from metadata, choose the former one. If the query result of  `min/max` aggregation is based on a left/inner join flat-table, query result from metadata is preferred.
