---------------------------------------
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.
