             Summary: Wholestage code-gen for ORC Hive tables
                 Key: SPARK-18540
                 URL: https://issues.apache.org/jira/browse/SPARK-18540
             Project: Spark
          Issue Type: Improvement
            Reporter: Damian Momot


Spark already optimizes hive parquet tables reading using whole stage code generation.

Similar approach could be used for scanning Hive ORC tables - currently standard hive table scan is used.

ORC is sometimes preferred over parquet in hive ecosystem because of better support and characteristics in certain scenarios
