[jira] [Commented] (SPARK-42988) Spark Sql insert into hive table dynamic partitions slow

    [ https://issues.apache.org/jira/browse/SPARK-42988?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17707096#comment-17707096 ] 

thomasgx commented on SPARK-42988:
----------------------------------

Use the same sql to execute on hive and spark, insert hive multi-level partition table, and find that in the stage of inserting partitions, hive is much faster than spark, and spark processes one file at a time during the processing process. What is the optimization in this place? What is the way, why not use the same move method as hive in spark
