             Summary: mapPartition to replace map to speedUp Dataset's toLocalIterator process
                 Key: SPARK-27185
                 URL: https://issues.apache.org/jira/browse/SPARK-27185
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.4.0, 2.3.0, 2.2.0, 2.0.0
            Reporter: angerszhu


In my case, I will use DataSet's toLocalIterator function, and I found that underlying code can be improved,it can be changed from map to mapPartitionsInternal to speed Up the process of  decode data to Internal Row
