Apache Spark reassigned SPARK-36210:
------------------------------------
Assignee: (was: Apache Spark)
> 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
> Priority: Minor
>
> 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.
