Cheng Su created SPARK-34924:
--------------------------------

             Summary: Add nested column scan in DataSourceReadBenchmark
                 Key: SPARK-34924
                 URL: https://issues.apache.org/jira/browse/SPARK-34924
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: Cheng Su


For the table scan benchmark `DataSourceReadBenchmark.scala`, we are only testing atomic data type but not nested column data type (array/struct/map) - [https://github.com/apache/spark/blob/master/sql/core/src/test/scala/org/apache/spark/sql/execution/benchmark/DataSourceReadBenchmark.scala#L544-L567] . We should add scan benchmark for nested column data type as well.
