> Key: IMPALA-10650
> URL: https://issues.apache.org/jira/browse/IMPALA-10650
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Qifan Chen
> Assignee: Qifan Chen
> Priority: Major
> Fix For: Impala 4.1
>
>
> 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.
