--------------------------------------
Summary: Apply and evaluate expressiosn row-wise in a DataFrame
Key: SPARK-37971
URL: https://issues.apache.org/jira/browse/SPARK-37971
Project: Spark
Issue Type: Improvement
Components: PySpark
Affects Versions: 3.2.0
Reporter: Carlos Gameiro
This functionality would serve very specific use cases.
Consider a DataFrame with a column of SQL expressions encoded as strings.
Individually it's possible to evaluate each string and obtain the corresponding
result. However it is not possible to apply the expr function row-wise (UDF or
map), and evaluate all expression efficiently.
