Nicholas Chammas created SPARK-37647:
----------------------------------------
Summary: Expose percentile function in Scala/Python APIs
Key: SPARK-37647
URL: https://issues.apache.org/jira/browse/SPARK-37647
Project: Spark
Issue Type: Improvement
Components: PySpark, SQL
Affects Versions: 3.2.0
Reporter: Nicholas Chammas
SQL offers a percentile function (exact, not approximate) that is not available
directly in the Scala or Python DataFrame APIs.
While it is possible to invoke SQL functions from Scala or Python via
{{{}expr(){}}}, I think most users expect function parity across Scala, Python,
and SQL.
