------------------------------------
Assignee: Apache Spark
> DataSource V2: Add default null ordering to SortDirection
> ---------------------------------------------------------
>
> Key: SPARK-34457
> URL: https://issues.apache.org/jira/browse/SPARK-34457
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.2.0
> Reporter: Anton Okolnychyi
> Assignee: Apache Spark
> Priority: Major
>
> The SQL standard does not define the default null ordering for a sort direction. That's why it is up to a query engine. We need to standardize this in our public connector expressions to avoid ambiguity. That's why I propose to match the Catalyst expressions.
