Hsieh resolved SPARK-36210. --------------------------------- Fix Version/s: 3.1.3 3.2.0 3.0.4 Resolution: Fixed Issue resolved by pull request 33423 [https://github.com/apache/spark/pull/33423] > Preserve column insertion order in Dataset.withColumns > ------------------------------------------------------ > > Key: SPARK-36210 > URL: https://issues.apache.org/jira/browse/SPARK-36210 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 3.1.2 > Reporter: koert kuipers > Assignee: koert kuipers > Priority: Minor > Fix For: 3.0.4, 3.2.0, 3.1.3 > > > Dataset.withColumns uses a Map (columnMap) to store the mapping of column > name to column. however this loses the order of the columns. also none of the > operations used on the Map (find and filter) benefits from the map's lookup > features. so it seems simpler to use a Seq instead, which also preserves the > insertion order. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
