Qifan Chen created IMPALA-10763: ----------------------------------- Summary: 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
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. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
