Josh Rosen updated SPARK-9143:
------------------------------
Shepherd: Michael Armbrust
> 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.
