----------------------------------------
Summary: Prepare ColumnVector implementation for UnsafeData
Key: SPARK-17915
URL: https://issues.apache.org/jira/browse/SPARK-17915
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.0.1, 2.0.0
Reporter: Kazuaki Ishizaki
Current implementations of {{ColumnarVector}} are {{OnHeapColumnarVector}} and
{{OffHeapColumnarVector}}, which are optimized for reading data from Parquet.
If they get an array, an map, or an struct from a {{Unsafe}} related data
structure, it is inefficient.
This JIRA prepares a new implementation {{OnHeapUnsafeColumnarVector}} that is
optimized for reading data from a {{Unsafe}} related data structure.
