> numPartitions is not specified
> -------------------------------------------------------------------------------------------------
>
> Key: SPARK-37523
> URL: https://issues.apache.org/jira/browse/SPARK-37523
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: Huaxin Gao
> Priority: Major
>
> When doing repartition in distribution and sort, if data source requests for
> a specific number of partitions, we should not optimize repartition. However,
> if data source does not request for a specific number of partitions, Spark
> should optimize repartition and split the skewed partitions if necessary.
