[jira] [Created] (SPARK-34457) DataSource V2: Add default null ordering to SortDirection

Anton Okolnychyi created SPARK-34457:
----------------------------------------

             Summary: 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


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.
