Summary: Direct consume UnsafeRow in wholestage codegen plans
Key: SPARK-13636
URL: https://issues.apache.org/jira/browse/SPARK-13636
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Liang-Chi Hsieh
As shown in the wholestage codegen verion of Sort operator, when Sort is top of
Exchange (or other operator that produce UnsafeRow), we will create variables
from UnsafeRow, than create another UnsafeRow using these variables. We should
avoid the unnecessary unpack and pack variables from UnsafeRows.
