[jira] [Created] (SPARK-23875) Create IndexedSeq wrapper for ArrayData

             Summary: Create IndexedSeq wrapper for ArrayData
                 Key: SPARK-23875
                 URL: https://issues.apache.org/jira/browse/SPARK-23875
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.4.0
            Reporter: Liang-Chi Hsieh


We don't have a good way to sequentially access {{UnsafeArrayData}} with a common interface such as Seq. An example is {{MapObject}} where we need to access several sequence collection types together. But {{UnsafeArrayData}} doesn't implement {{ArrayData.array}}. We can provide an {{IndexedSeq}} wrapper for {{ArrayData}}, so we can avoid copying the entire array.
