----------------------------------------
Summary: Add InternalColumn
Key: SPARK-13437
URL: https://issues.apache.org/jira/browse/SPARK-13437
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Kazuaki Ishizaki
To abstract a columnar storage, it would be good to introduce {{InternalRow}}
as an analogy with {{InternalRow}}. This would allow us to use different
implementations of column storage.
For now, {{ColumnarVector}} extends {{InternalRow}}.
