Hi, You can ignore my question, Found the relevant JIRA - https://issues.apache.org/jira/browse/IMPALA-2017 So I guess the answer is not yet.
Regards, Antoni From: Antoni Ivanov Sent: Tuesday, March 20, 2018 9:45 AM To: 'user@impala.apache.org' <user@impala.apache.org> Subject: Does Impala supports or plan to support Late Materialization I don't mean partition pruning but as described in https://aws.amazon.com/about-aws/whats-new/2017/12/amazon-redshift-introduces-late-materialization-for-faster-query-processing/ It basically pre-fetches first the filter columns and then after applying the filter it fetches only the data from the rest of columns only if filter applies. Thanks
