---------------------------------
Summary: Add planner rule for automatically inserting Unsafe <->
Safe row format converters
Key: SPARK-9143
URL: https://issues.apache.org/jira/browse/SPARK-9143
Project: Spark
Issue Type: New Feature
Components: SQL
Reporter: Josh Rosen
Assignee: Josh Rosen
Now that we have two different internal row formats, UnsafeRow and the old
Java-object-based row format, we end up having to perform conversions between
these two formats. These conversions should not be performed by the operators
themselves; instead, the planner should be responsible for inserting
appropriate format conversions when they are needed.
