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
