[jira] [Created] (IMPALA-11037) Bump ORC to 1.7-p4 to contain the improvement of ORC-1020

Quanlong Huang created IMPALA-11037:
---------------------------------------

             Summary: Bump ORC to 1.7-p4 to contain the improvement of ORC-1020
                 Key: IMPALA-11037
                 URL: https://issues.apache.org/jira/browse/IMPALA-11037
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Quanlong Huang
            Assignee: Quanlong Huang


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.
