    Description

      ORC-1020 improves read performance of the ORC library in scanning random integers. Columns that encoded into integers, e.g. dictionary encoded strings, will also benifit from this.

      This Jira aims to add ORC-1020 to our native-toolchain and bump our orc version to 1.7-p4 to contain it.
