-------------------------------------------
Summary: Allow predicate for pyspark.sql.functions.array_sort
Key: SPARK-35970
URL: https://issues.apache.org/jira/browse/SPARK-35970
Project: Spark
Issue Type: Wish
Components: SQL
Affects Versions: 3.1.2
Reporter: Ramanan Subramanian
Currently, both the Python API and the Scala API for the SQL function
`array_sort` do not take a predicate boolean function/lambda expression as a
second argument. Hence, we have to resort to `expression` or `selectExpression`
and use the DSL for the predicate function. It would be nice to allow this,
just like all the higher-order functions.
