--------------------------------------
Summary: Pass objects as parameters to SparkSQL UDFs
Key: SPARK-35524
URL: https://issues.apache.org/jira/browse/SPARK-35524
Project: Spark
Issue Type: New Feature
Components: PySpark, Spark Core, SQL
Affects Versions: 3.1.1
Reporter: Julian Shalaby
You can pass class objects directly to UDFs using the UDF format:
df.select("*").filter(myFunc(classObj)(col("colName")))
but the format:
"""SELECT * FROM view WHERE myFunc(classObj, "colName")"""
or
"""SELECT * FROM view WHERE myFunc(classObj)("colName")"""
does not work. This would be a very useful feature to have, especially being
that UDTs are being made public again in 3.2.0
