Fix Version/s: Impala 4.0
Resolution: Fixed
> Improve always-true min/max filter handling in coordinator
> ----------------------------------------------------------
>
> Key: IMPALA-10647
> URL: https://issues.apache.org/jira/browse/IMPALA-10647
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Qifan Chen
> Assignee: Qifan Chen
> Priority: Major
> Fix For: Impala 4.0
>
>
> Currently, when a just arriving min/max filter is the last one to arrive or
> is always true, the coordinator disables the corresponding filter
> representation by setting it to Always True. This makes it impossible to
> differentiate a true AlwaysTrue filter (say, set in the
> hash join building step) from the one being disabled.
> A better handling is needed in this area.
