[jira] [Created] (IMPALA-10650) Bail out min/max filters in hash join builder early

Qifan Chen created IMPALA-10650:
-----------------------------------

             Summary: Bail out min/max filters in hash join builder early 
                 Key: IMPALA-10650
                 URL: https://issues.apache.org/jira/browse/IMPALA-10650
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Qifan Chen


Currently, a mechanism is in place to set a min/max filter to always true (not useful) after all batches of rows are inserted into the hash table, utilizing the column stats.  While quite helpful, the mechanism does not exploit the property that the same not useful state can be reached as soon as several batches are inserted.
