Dongjoon Hyun updated SPARK-30569:
----------------------------------
Affects Version/s: (was: 3.0.0)
3.1.0
> Add DSL functions invoking percentile_approx
> --------------------------------------------
>
> Key: SPARK-30569
> URL: https://issues.apache.org/jira/browse/SPARK-30569
> Project: Spark
> Issue Type: Improvement
> Components: PySpark, SQL
> Affects Versions: 3.1.0
> Reporter: Maciej Szymkiewicz
> Priority: Major
>
> Since 2.1 (SPARK-16283) Spark provides {{percentile_approx}} SQL function,
> however it is not exposed through DSL, with exception to
> `DataFrameStatFunctions.approxQuantile` (which is eager and doesn't support
> grouping).
> It would be useful to have it exposed through {{o.a.s.sql.functions}} /
> {{pyspark.sql.functions}}.
