> Limit improperly pushed down through window using ntile function
> ----------------------------------------------------------------
>
> Key: SPARK-40002
> URL: https://issues.apache.org/jira/browse/SPARK-40002
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.3.0, 3.2.2
> Reporter: Bruce Robbins
> Assignee: Bruce Robbins
> Priority: Major
> Labels: correctness
> Fix For: 3.3.1, 3.2.3, 3.4.0
>
>
> Limit is pushed down through a window using the ntile function, which causes
> results that differ from Hive 2.3.9, and Prestodb 0.268, and older versions
> of Spark (e.g., 3.1.3).
> Assume this data:
> {noformat}
> create table t1 stored as parquet as
> select *
> from range(101);
> {noformat}
> Also assume this query:
> {noformat}
> select id, ntile(10) over (order by id) as nt
> from t1
> limit 10;
> {noformat}
> Spark 3.2.2, Spark 3.3.0, and master produce the following:
> {noformat}
> +---+---+
> |id |nt |
> +---+---+
> |0 |1 |
> |1 |2 |
> |2 |3 |
> |3 |4 |
> |4 |5 |
> |5 |6 |
> |6 |7 |
> |7 |8 |
> |8 |9 |
> |9 |10 |
> +---+---+
> {noformat}
> However, Spark 3.1.3, Hive 2.3.9, and Prestodb 0.268 produce the following:
> {noformat}
> +---+---+
> |id |nt |
> +---+---+
> |0 |1 |
> |1 |1 |
> |2 |1 |
> |3 |1 |
> |4 |1 |
> |5 |1 |
> |6 |1 |
> |7 |1 |
> |8 |1 |
> |9 |1 |
> +---+---+
> {noformat}
