Subject Does Impala supports or plan to support Late Materialization
Date Tue, 20 Mar 2018 07:45:08 GMT
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
