             Summary: Introduce additonal implementation with a dense format for UnsafeArrayData
                 Key: SPARK-15962
                 URL: https://issues.apache.org/jira/browse/SPARK-15962
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Kazuaki Ishizaki


It would be good to have an additional implementation, which uses dense format, for {{UnsafeArrayData}} to reduce memory footprint. Current {{UnsafeArrayData}} implementation uses only a sparse format.
It is useful for an {{UnsafeArrayData}} that is created by a method {{fromPrimitiveArray}}, which have no {{null}} value.
