                 URL: https://issues.apache.org/jira/browse/IMPALA-6506

          Issue Type: Improvement
          Components: Backend
            Reporter: Quanlong Huang

Currently, the orc-scanner materializes tuples from the orc-reader (ORC lib). 
We need a Codegen implementation in TransferScratchTuples for the runtime 
filter + conjunct evaluation loop.
