-----------------------------------
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.
