-----------------------------------
Assignee: Qifan Chen
> Min/max filters should be enabled on Z-order sorted columns
> -----------------------------------------------------------
>
> Key: IMPALA-10763
> URL: https://issues.apache.org/jira/browse/IMPALA-10763
> Project: IMPALA
> Issue Type: Test
> Reporter: Qifan Chen
> Assignee: Qifan Chen
> Priority: Major
>
> Currently, min/max filters are enabled for lexically sorted columns (please
> refer to
> IMPALA-10709: Min/max filters should be enabled for joins on sorted columns
> in Parquet tables) with a limitation that only the leading sorted columns are
> assigned with min/max filters. Non-leading sorted columns will be ignored.
> To effectively handle multiple sort columns, Impala offers an alternative
> sort order called Z-order. Z-order sorts these columns in multi-dimension
> into a sequence of values such that the locality of the data points are
> preserved.
> The purpose of this JIRA is to integrate the min/max filter feature with a
> table with Z-order sorted columns.
