XiDuo You updated SPARK-38578:
------------------------------
Summary: Avoid unnecessary sort in FileFormatWriter if user has specified
sort in AQE (was: Avoid unnecessary sort in FileFormatWriter if user has
specified sort)
> Avoid unnecessary sort in FileFormatWriter if user has specified sort in AQE
> ----------------------------------------------------------------------------
>
> Key: SPARK-38578
> URL: https://issues.apache.org/jira/browse/SPARK-38578
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: XiDuo You
> Priority: Major
>
> FileFormatWriter will check and add an implicit sort for dynamic partition
> columns or bucket columns according to the input physical plan. The check
> became always failure since AQE AdaptiveSparkPlanExec has no outputOrdering.
> That casues a redundant sort if user has specified a sort which satisfies the
> required ordering (dynamic partition and bucket columns).
