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

             Summary: Min/max filters should be enabled for joins into sorted columns in Parquet tables 
                 Key: IMPALA-10709
                 URL: https://issues.apache.org/jira/browse/IMPALA-10709
             Project: IMPALA
          Issue Type: Test
            Reporter: Qifan Chen


Currently, the min/max filter feature is turned off by default (MINMAX_FILTER_THRESHOLD=0). 

When joining into sorted columns in a fact Parquet table, the feature can be turned on by default since the filter can achieve maximum filtering efficiency.
